Lets be realistic, that's most people. Everyone thinks their pet causes to get offended about are justified. Even people getting indignant about cancel culture are enjoying their indignation.
There's a difference between laughing at and being outraged by. Pointing and laughing is perfectly reasonable, getting bent out of shape over imagined slights is paranoia.
Despite you using the word 'funny' I don't think you were laughing while posting that whereas the GP was.
I think that's too generous. I've definitely met people who just enjoy feeling indignation at anything.
