That sucks, OP. I totally know what you mean :\ We're not all like that! People should at least have more than one fandom they can reference, if they have to reference fandoms all the time, FFS. Hell, I went all summer and most of the fall without touching DW because I was exploring other stuff, and IMO I like it better when I haven't seen it in a while. Everything's fresh and new and fascinating and you notice all those little unique things! Which is true of any show, I suppose. Those obsessed fans are just...obsessed and weird and they just so happen to be obsessed with Who.

Also, I assure you, by my years of experience with Harry Potter, that in any fandom ever, that contingent of fans - y'know the one, every large geeky fandom has one - are obsessed and obnoxious because of the nature of their personalities, not because of the nature of the show. If they weren't obsessed with Who, they'd be obsessed with something else. It's like they view it as a malicious personal insult if you don't want to watch what they like watching, plus they feel superior at the prospect of "introducing" someone to a new fandom or something.
