I can't stand when people do this. Even people who are close to me think its stupid and don't understand, and sometimes say comments that are a bit insulting to me
It's ridiculous that people can't realize that we're not all the same, we all won't like the same things, and if you have an opinion about something fine, but don't try to be insulting about it. That doesn't work. (sorry - my friend has been doing this, not just about anime/manga too!).
