Why do people hate HP on these forums?

I don't think anyone hates any franchise. What people hate is when those defending said franchise hold so heartedly to their opinion, are completely dismissive, and so certain that their biased view trumps any other that the debate becomes pointless.

He had a previous account called "MasterJohn" and he kept making threads that just seemed to stir up trouble,like threads talking about why he think violent video games are bad or that abortion is wrong etc.Eventually he got banned due to them.

Now it seems he is back to making similar threads but this time with a Harry Potter theme.Maybe not though,maybe only two threads this time.

Might sound like I am talking bad about him,well I am not go check his previous account if you don't believe me.
