What about a play titled "All Gays burn in hell"? Is that hate speech or freedom of artistic expression.
If it's a play, seems fair to me. I don't believe in censoring such things - it can open people's eyes.
I actually think there could be some artistic merit in it, particularly if it was from the point of view of typical blokersi. They are so woefully unrepresented in the arts that it's about time that someone did something from their point of view.
Or writing an op-ed saying homos should be imprisoned or deported? Hate speech or freedom of expression?
Hate speech, without a shadow of a doubt.
Citing research showing that homos have a higher STD rate than heteros? Hate speech or documented medical evidence?
No harm in citing research as long as the right of rebuttal is there.
Maybe they can charge Polish citizens, but they have exactly zero, zilch, nada chance to prosecute someone in the USA for hate speech which targets Polish nationals. There is something called freedom of speech here, and nobody will take that away. It's naive to believe otherwise.
Only a point, but if the prosecutor in Poland shows interest in the case and gets a European Arrest Warrant issued, it could make life very difficult for the person in question. You're right that the USA wouldn't show much interest in deporting the person (they show much more interest in getting people deported to the US for trivial things...) - but that person could easily get arrested in London and extradited to Poland for what they've said online.
Having said that, American citizens seem to be quite able to dish out vigilante-style justice online...
