Then let me rephrase it, because I forgot it's the internet and people will try to misunderstand me. As a member of a non-specified group X, I would hate it if people would precondemn me based on thing Y, which a part of group X does more than the average population. I could have picked any other stereotype, I just happen to be not a woman, and of the majority ethnicity in my country. Blame my parents. However, based on this hypothetical, yet relatable thought experiment, saying that a group does a bad thing because some people who happen to be in that group do that bad thing more often than other people is at the very least rude.
