What people find offensive can vary greatly from person to person and one culture to another. Morality can be pretty different between different religions and cultures, and the same holds true for what is considered truly insulting or offensive.

I think the most offensive idea/thing I was ever told was that because I have two dads and am not straight (not gay either, but not straight), that they must have messed me up.
That's like... next level homophobia.
That and racism/antisemitism. And people who hate on disabled folks. Like I don't get that crap. My aunt is in a wheelchair and she literally got yelled at in public once for being a "drain on society" cause she asked some dude to get her some cereal off the top shelf. I don't get that crap? Just... be nice to people, damn. raleighwh2001
