... Frankly, we really don't need any more people around here trying to 'fuck shit up.' I think people just recovered from having PTSD over the last time somebody tried it. The community is generally very welcoming here, no one felt the need to "deal with" you coming here, though they may if your intention really is what you said.
I don't really get your introduction, either. Why, exactly, would you make your first post and first impression here something you feel the need to apologize for? If you already felt bad about it, posting it was foolish.
