I guess you missed when Kathy Griffin was arrested along with those actors in NY that were murdering Trump or that State Senator that called for his assassination
You'd be better off by not confusing fiction with reality. Robert Zemeckis was not expressing some underlying intent on becoming an idiot shrimp fisherman when he directed
Forrest Gump. Nor was he announcing his intent to time travel by directing the
Back to the Future franchise. Probably had no plans on becoming a cartoon train conductor with
The Polar Express.
Giffin's an idiot for sure, but I didn't miss the part where Kathy Griffin was actually being investigated by the Secret Service at one point for conspiracy to assassinate the President. I also didn't miss the part where a tall, slender, black man played Julius Caesar in 2012. Actually, scratch that. I missed every bit of it until the 2017 production made the news because this year's depiction was Trump. Were you aware of the 2012 version? If we wanna talk about poor statements outside of the "arts", I recall the good friend of Donald Trump and draft dodger, Ted Nugent, and his empty threats:
"If Barack Obama becomes the president in November, again, I will be either be dead or in jail by this time next year."
Not that I'm trying to compare dumb statements here because this probably isn't a road anyone should have any interest in going down. It'd be a waste of time. I bring up Ted -
a man who admittedly, and literally, pissed and pooped his pants for multiple weeks to avoid the draft - because even his comments are not intents to harm. They are likely as close as you can find, but I don't think they actually are. Why? Because I know he's all schtick, and his schtick is saying outlandish things. He's a caricature of an American, at best. Kathy Griffin is a caricature. Julius Caesar was a character. Random senator is not, but wishing death on someone is not expressing intent to make it so.
Random people sending explicit intents to harm are not stupid statements made by caricatures. They haven't built a career out of saying stupid things the way Giffin and Nugent have and they are most definitely venturing out of the, "just wishing", area. Furthermore, those people don't have the luxury of well-paid attorneys to get them out of a pinch.
If you can't draw a distinction between theater and art
(And I wouldn't even call Giffin's picture, 'art'. It barely qualifies as photography and it's a step or two below all the, "it's just a prank, bro", type of videos that have infected YouTube), and a communication of intent to end someone's life then I don't know what to tell you. Even wishing death upon someone is distinct from expressing intent to kill them, which is why wishing people die isn't a crime while telling someone you are going to kill them is a crime.
Sorry, those are the boundaries we live with. Somehow, most of society has been able to live with such a distinction but to each their own, I suppose. Death threats are illegal. You may produce a play that depicts a person's death if you like, and you can even direct a movie that depicts as much.
Kingsman: The Secret Service had a nice depiction of a black US President and those around him having their heads explode while Randy Savage's intro music was playing. Yes, the line is somewhere in between the two. Is this really so hard to figure out? Are you new to this country? ESL, maybe? At least then your confusion would be understood. If not, then I guess you're just paying the fool?
