Why do a lot of people complain and think there should be a seperate site for minors?

I've heard a lot of complaints about people wanting to kick minors off of Yahoo Answers or get them on a different site. This makes me very mad! I am four teen and I honestly try to answer questions to the best if my abilities, and I have seen adults who act horribly immature on this site, yet people complain about how minors act. I agree that minors do act rudely but in my eyes, if someone doesn't want to deal with minors and their questions they should not pay any attention to it in the first place. I'd rather hang out with adults any day, so do you think minors should have a seperate YA site?
