Still a generalization. You focus on the worst and wanna change the meaning of the word to reflect that. Like if someone sees an African American teen gang and wants now the term "African American" to refer exclusively that, instead of, you know, the sea of other people that are of that ethnicity. Sorry, but until you are able to prove a correlation between the category and the behavior, other than 'it' s a category so big that of course assholes will also be a part of it' it's a simple generalization that doesn't hold to scrutiny. Also, you are free to give the meaning you want to words, just don't pretend the rest of the world must follow you in this behavior.
