Your inability to take critisizm is your problem. Welcome to the internet. If you do something stupid, people will flame. If you have no common sense, people will flame. If you are a loving noob, people will flame. I've said this before on other topics and I'll say it again: there are no real social repercussions on the internet for most people. Therefore, they will actually state exactly what is on their mind. This isn't real life where you have to put up with people day after day and have to make yourself likeable.
As Jirue said, the new guy is always on the stuff end of things. I remember joining, being stupid, getting flamed, banned, and growing up bit by bit. No one ever said that being accepted was easy. In real life, people may act nice to you to avoid hurting your feelings. They may even go so far as to accept you into their group. But this doesn't mean that you aren't still heavily critisized behind your back. It's time to decide if you want people to be nice or honest. Pick or gtfo.
