The fan base is so wide, I could probably think of all sorts of things that bug me, but that could be said about everything I guess. That considered it could be much worse.
However I completely agree with your points, especially #4. That is something I find to be very off putting on this forum. I guess everybody's liable to their own opinion, but they often do come off as obnoxious making those kinda of statements.
I gotta say, considering people are always stating how "mature" and "not just for kids anymore" this series is, there's a lot of very childish statements being posted in this place, IMO. That's not necessarily a bad thing, see as I'm not actually sure what age most of the people are that post here are; it's just an observation I've made.
Whatever though, I'm not perfect. I probably bug a lot of people with my posts
