Let's put another hypothetical example.
A nigger assaulted me in the middle of the street. He beat me up, then he robbed me. Ever since, I have had an irrational fear of every person with dark skin, whether they are black or not. I get PTSD every time I get too close to one. Should you ban black people from appearing in comics to avoid triggering me?
Next example: some people have some really hard arachnophobia and may get cold sweat from even looking at shapes resembling a spider. Should we ban Spider-Man and his logo?
Another example: this is real, some people find FUCKING BALLONS triggering. Yeah, that's right, some people turn into screaming puddles of tear the moment they see a balloon. If it sounds ridiculous it is because it is, but it is a very real fear for these people. Should we ban balloons and depictions of balloons?
Some personal example: listening to UVB-76's buzzing triggers some of my most primal fears, and I don't know why. Apparently I am not the only one who is scared shitless of that sound, judging by the time I asked on /x/. Should we find UVB-76 and shut it down, or alternatively, make all radios skip its frequency?
You mentioned the word "bullying". Turns out there is someone out there who was beaten up as a kid while the other kids chanted "bullying! Bullying! Bullying!" in unison. As a result, he now cries whenever he reads or hears the word "bullying" or anything that sounds similar, like Ferran Adria's restaurant "El Bulli". Whoops, you will have to delete your post and rewrite it again without using that word. I will also notice Ferran Adria that he has to change the name of his restaurant immediately.
Some people are allergic to water. Should we ban water installations in all houses?
And now the punchline: some people actually find some topics other people find disgusting to be therapeutic. Reading rape stories may trigger some girls who have been raped, but other girls who have been raped may find comfort in reading about other people's experiences. Should we ban these people's relief, or should we keep these other people's triggers?
You can't please everybody. If we ban everything because it may be offensive to someone, we would end up being able to do nothing. We should all lie immobile in a flat desert ground, naked… whoops, no, that's triggering for some people. Just become transparent.
