You know... Humor is an important way to show bad things. And don't think you are the only crime victim. I've had my own share as well, and even worse, the cops were very extremely rude to me when I reported those at the police department.... And I've also been through many other bad things... Jokes about those kept me alive. Jokes about the most terrible things is actually the most important thing that keeps everybody alive.
You may not like them, but the joke in the meme is actually rather a statement about the NRA itself than ridiculing the right to carry a gun and people who have been looking inside a gun itself, so maybe you need a clue about the meme it self, as you took offense over nothing.
Yes, we do know that the humor that keeps us alive my sometimes fall bad to some people, for understandable reasons even. However don't act like the anti-humor guru over these matters. Especially since this joke is rather a political statement, and an important one too. Jokes have always been the most important way to make statements like these.
I understand your trauma. Really I do... I've tons of traumas of my own, to be honest that you can scarcely imagine. Death threats not even been the worst thing I've endured. But I know one thing. You protest does rather come in as a way to block the statements about the NRA... Important statements that have to be made and with that you make an attack on democracy, and national security all over a personal trauma. A bit selfish, don't you think?
"Get a clue", eh???? Who's the one being clueless now?
