I think we can all learn a valuable lesson from all of this:
Calm the fuck down and quit freaking out about what other people do, especially if it doesn’t directly affect others. If someone makes a joke, let it just be a joke and don’t try to make them feel bad about it. Otherwise you’re probably causing far more damage than the initial “problem” would have (if it would have caused any damage to anyone in the first place, which is unlikely). Someone joking about people dying is just a person who makes untactful jokes. That person is not a “monster”. Someone who hurts innocent people is a monster. Anything short of that is perfectly okay.
Tumblr, and most liberal people in general, are heavy advocates of issues like equality and gay marriage. This is a good thing. But at the same time, most of these people will condemn the FUCK out of someone for their creative choices, just because they believe that it’s offensive.
“Oh no you referenced a group of people who committed genocide 50 years ago in your cosplay! You’re an awful human! And I say this despite not personally knowing anyone who was affected by this, since I am a teenager and it was 50 years ago, and despite the fact that I watch shows about serial killers and find no problem with that, since the serial killer is not associated with any real group of people.”
“How dare you joke about the bombing in Boston or that school shooting? Making light of this situation is literally 100% as bad as doing it yourself! You are required to pretend to be sad about the misfortune of people you don’t know, or else you are evil.”
Note that, while these quotes are not exact, they are entirely equivalent to actual things that I have seen people say because of these issues.
Do you see the problem here?
