You realize that there's more difference between your average man and your average woman than between your average NFL linebacker and your average man, right? (seriously, compare the stats some time - height, average bench strength, etc). You do realize how commonly women are raped and abused by men, and how they might happen to be more sensitive to the implicit or explicit threats of violence from someone that they're highly unlikely to be able to fight off?

I'm tall, 182 centimeters, and I still once had a guy literally pick me up and carry me back to his apartment when I tried to walk away from him.

There's a bit of a difference in that one in every four women actually will be raped in their life, and a sizeable percent of those getting those threats already have been.

Yes, men are raped too. About 91% of rape cases are male->female, 8% male->male, 0.8% female->female, and 0.2% female->male. Men are virtually always the perpetrator, but even when the victim is male (not nearly as common, but still way more common than we as a society should accept), the perpetrator is still overwhelmingly likely to be male.

(and if the excuse for the stats is "men aren't as likely to report being raped by a woman because of shame"... so is there no shame for a guy to report being sodomized against his will by a man?)

The basic point is: when you're threatening a violent crime against a person who may well have been a victim of such, and even if they haven't, very likely has friends who have and is more than aware of their vulnerability in this regard, that's taking it to a whole different level.

Nice being a straight cis white male when a venue is dominated by other straight cis white males, isn't it?

And just to make clear, the problem of insulting people isn't along the lines of "ching chong chow chee" or whatnot. The problem case is along the lines of:

Scenario 1:

Man: "What does that do? Sorry, I don't know perl."
Crowd: "You don't know perl? Geez, you're stupid."

Scenario 2:

Woman: "What does that do? Sorry, I don't know perl."
Crowd: "Geez, women are stupid."

Contary to popular belief, broomsticks can't fly and are not aerodynamic.

If 16th century India could do it... (why a person would believe that the warhead has to be the frontmost part of a rocket is beyond me, given that the interceptors themselves aren't built that way - yet the entire logic behind the interceptor's detonation system relies on that assumption)

In any case the missile will miss its intended target if it was hit by shrapnel.

Nope.

1. A hit by a few pieces of shrapnel each weight no more than a few grams is not going to have a noticeable impact on something that's dozens of kilograms moving at roughly half their speed. It's simple physics.

2. The warhead is the whole point. A warhead-less rocket won't penetrate your roof. If you're out walking in the park and it lands on your head you might get seriously injured, but apart from that. no.

3. What are you talking about? The payload of the Tamir interceptors is is 11kg, that's no secret. And again, it's not designed to work by concussion, it's designed to work by shrapnel. The energy of the explosion is mostly spent in the process of creating high velocity shrapnel fragments.

Beyond that, the length of time of any exposure here to any explosive force is simply miniscule. The rockets pass each other at a rate of 1200 meters per second - nearly half the speed of the explosive shrapnel itself. Even if they passed directly past nearly grazing each other (which is grossly implausible), they'd only be within a meter of each other for less than two milliseconds. And even things that are right near explosions the whole time get surprisingly little push from blast shockwaves (Mythbusters did a full episode about this). Relevant push from explosions requires confinement of the gasses.

Israel's GDP is the equivalent of about US$250 billion. They can easily afford tens of thousands of intercept missiles if it keeps the population safe.

And Palestine's is 4B GDP. Yes, they're poor, but not *that* poor. They can afford to spot weld fins onto a piece of drainage pipe, drill holes into a bit of steel plate and spot weld it on, fill it with sugar and fertilizer, and attach onto the front end a hollow shell containing several kilos of smuggled or homemade explosives triggered by a bullet casing connected to a nail and a spring. That's literally all a Qassam rocket is.

Iron Dome isn't designed to hit rockets in the boost phase; when it hits them, the motor is not in operation. You could turn 90% of the rocket into swiss cheese, if you don't hit the warhead it's still going to explode when it comes down, and it's going to come down right where it otherwise would have (the Iron Dome interceptors work by shrapnel, not by concussive force that could push a rocket onto a different trajectory)

Here's a Qassam rocket. When they're new they often paint them up all fancy, but you can see how simple they are without the paint. They're just a steel pipe with fins crudely welded to the side. The engine is a steel plate with nozzles drilled out. They use multiple nozzles because the rockets are so crudely made, they keep on going even if a couple fail. They're literally sugar rockets - the fuel is sugar and potassium nitrate fertilizer. The warhead is a steel shell which they stuff with whatever smuggled explosives they can get ahold of. The trigger is a bullet cartridge with a nail and a spring.

Teenagers competing in model rocket competitions build more advanced rockets than that.

Given how incredibly lame this missile's fuse is, you could literally defeat it by sticking a broomstick on the front end of your missile and rebalancing. That is, if the system even worked in the first place.

I had no idea that's how they triggered the Iron Dome warheads. Just a broken, angled light field triggering a central explosive a short time later on the premise that it'll be near the warhead at that point? That's so incredibly stupid. I don't know whether this guy's data about how effective the system is or not is accurate, but I can clearly see the glaring theoretical problems with such a system.

And this is ignoring the fact that they're using $50k missiles launched from $55 million systems to shoot down $800 rockets launched from pieces of drainage pipe. Even as poor as Palestinians are compared to Israelis, those are some pretty awful ratios. The Palestinians might as well save money and skip the warheads altogether, just shoot off as many empty rockets as they can to waste Israel's money.

Orders of magnitude are used for approximations of scale, not exact figures. And the Russian R-36 missile can take a 20MT warhead (although I think they've eliminated all of the R-36s in that configuration in favor of the MIRVed version, I'd have to check).

You're right, though, I think two orders of magnitude would be a more accurate figure.

An Ada exception is when a routine gets in trouble and says 'Beam me up, Scotty'.
