Contrary to what you say, you can be aggravating and you can even try to deliberately aggravate people without breaking the law! Think of those "god hates fags" morons. That's pretty much as hateful, stupid, and aggravating as you can get, but it's still protected speech.
"fighting words" and "incitement" are illegal acts in many places, and there's a fine line for what are illegal words.
Yes, it certainly does. A sudden splash that opaques your windshield and/or distorts your view -- which a water balloon can most definitely do -- can startle and disorient the driver, leading to dire consequences. Throwing water balloons at vehicles is not a harmless prank. It is a thoughtless act that can directly endanger others. It is shortsighted and naive to characterize it any other way.
So assume they hit the roof, a startling sound, but no impairment to vision. If the driver reacts and crashes, is that the fault of the person reacting, or the person acting?
In my experience people who were too lazy to learn perl in the mid 90s and who are not experienced in Java.
Isn't ignorance the lack of knowledge? Sure, wasting lectures on the willfully ignorant is a waste of time, but on the mere ignorant?
A race-baiting A/C is assumed willfully ignorant.
Offense is nothing like physical force, which is what a water balloon imparts.
So if I blow on your hand, I've used "physical force" and thus committed an assault? Does it matter of the "blowing" of air was from speaking? I can measure the "physical force" speech causes. Microphones are designed to measure and record that physical force.
But you have an inarticulable line between speech and "force" where the force has no force.
For the water balloon, what if it misses the car, and the driver still panicked and crashed?
Offense is like a water balloon thrown from a bridge at a passing car.
The water balloon constitutes physical interference with your property, your path, and your ability to drive in a safe manner, thereby additionally and (further) irresponsibly constituting risk to yet others via potential secondary and tertiary effects
So water hitting your car causes risk. I guess you never drive when rain is predicted.
In reality, a water balloon thrown at your car holds a near-zero risk. Yet people go ape-shit over it. Is the problem the person that causes offense, or the person that over-reacts? You assert that if it's assault with water, then it's the fault of the thrower (do you sue God every time it rains?), but if it's words, the fault is with the people that hear.
I think your logic is flawed.
Does it matter if the "offensive language" is an adult trying to talk a mentally ill minor into suicide?
This is not "offense." This is incitement and inappropriate exercise of power. You are moving the goalposts quite a distance here.
I'm taking a real incident of speech that was prosecuted. You speak in platitudes and generalities, but nothing concrete and definable. So I'm trying to identify the edges, if any. Inciting someone to do something through speech should be illegal, according to you. Unless that "something" done is be offended. I don't see your logic. Offense is real, and measurable. It can be measured with medical tools, like you can see a bruise on someone's nose when you hit them. Yet the nose is sacred to you, and the ears aren't.
There are billions poured into STEM, and encouraging early career scientists through programs at NSF, NIH, DARPA, etc. None of that is working (less than 50% of people trained in science stay in science). When I was still training students, the best of them generally ended up working in finance, not physics. An additional $250 million is not going to make a notable difference. We need a cultural and structural change in how we train and retain good scientists and engineers, not a meaningless bandaid.
