Well, here's the thing for me. Everyone has the shows that they love and the fandoms they are a part of for a reason. But pretty much everyone also eventually leaves said fandom for one reason or another. So really, you're entitled to have your opinions about why you're done with Harry Potter and I don't think you should apologize for that :). Plus, I never got the impression at all that you were being rude or insulting to anyone with that post.

So yeah...you have your reasons, and as far as I'm concerned - that's good enough! Doesn't matter if people agree with them or not, as long as you feel okay about the decision to leave the fandom *hugs* :)
