What's to say they will not have actually learned anything or grown beyond their imperialist phase by the time they are so advanced?

That's not really the argument, is it? By the time they're that advanced, we have nothing they need. If we have anything they want, it's either food or culture. Maybe sentients are a delicacy, so that's a potential threat, but otherwise we'd be more valuable as we are — producing art, literature and so on. Then they can point at the monkeys and laugh.

Aliens that are advanced enough to signal us with that kind of power aren't going to find us advanced enough to be worth talking to if they can even understand our primitive methods of communication at all.

Sometimes we make noises that will attract animals so that we can study them.

The speed is less important than energy delivered at site of impact. [...] Fan rotors move slower, but are more massive, and have more total energy behind them. You dont need something to be sharp or fast moving to cut you in half; it just needs to exert enough energy over a small area to cause mechanical shear of your body.

Okay, let's try to stay on topic.

Getting a loop of wire from a wench wrapped around a leg and slowly slooped up will chop it off just as surely as if the wire was moving fast but at less torque.

Unless the wire catches on a bone, and the wire is thin enough to snap there. But let's fucking stay on topic. We don't need ridiculous examples designed to distract people because they contain an injury to discuss the topic at hand, you sensationalist nutter.

In fact, there are multiple factors involved in determining how much force it's going to require to break the silly string, and in how much force is being delivered. One of the factors is the force applied, one of the factors is the time in which the force is applied and how that affects the material in question, one of the factors is the quantity of material the force is being spread out across. And in spite of being a lot smaller and less massive, the tip of a quadcopter blade is going to impart a lot more energy to a much smaller section of silly string than a metal fan blade is, because the fan blade is squared off (being stamped from a piece of metal) while the tip of a rotor is very sharp, and the rotor is moving much much faster and F=MA. There's a lot more A in the quadcopter system. But wait, there's more; you only have to consider the effect of its mass until the string breaks. If the string breaks at a level of force which can be achieved with the current acceleration at lower than the actual mass, then the additional mass of the rotor is irrelevant here.

There are lots of other factors, but these are the ones that we've been talking about in this discussion already.

To be a proper experiment, it needs to be a high speed metal bladed fan, with big heavy blades. I can probably find one if I look hard enough.

Only the speed is likely to be relevant, and it will still have a dramatically lower tip velocity than a quadcopter doing anything but hovering.

So you mean the external renaming to 'Clinton News Network' was only because the letters matched?

Clinton is not a liberal. She is a neocon. Trump is not a conservative. He is just a sleazebag.

I never said she was a liberal, historically liberals believe in personal liberty... she does not. She's very much a illiberal progressive.

What? You just contradicted yourself there completely, smart guy. Care to rephrase your sentence until it makes sense? Here, this might help. Don't go alone, take one of these. Maybe then you'll have some idea what the words you're using mean.

A thought occurs to me. Functionally, a desk fan with metal blades is an appropriate analog for a drone rotor if the housing is removed.

Aside from the speed not even being in the same ballpark, sure. If that doesn't work, then it certainly won't work on a drone. If that does work, it might work on a drone, or at least, one which is only hovering and not actually going places.

Umm... you really think shooting at a flying bomb overhead is a GOOD idea? If so, remind me to steer clear of you.

Bomb is extremely hyperbolic. "Incendiary device" is the term you're looking for there. Unless, of course, it runs on compressed hydrogen (or another flammable gas) with a fuel cell.

Even I, a person who's never even held a gun, knows this is a fucking stupid thing to do.

Even you, a person who's never even held a gun, should shut the fuck up until he learns how firearms work. There are lots of pistols which are designed to be carried with a round in the chamber, probably most notably including 1911-pattern handguns.

People like you are the reason why people think anti-gun activists are morons.
