The classic one is that pedos can't connect with adults, or have adult (non-sexual) relationships - that's kind of ancient and as far as I can tell has no basis in reality. My main problems with adults is that I find most of them unpleasant in one or multiple ways so want nothing to do with them for that reason.
Movies - yes. No one's bothered me about not having a GF, or asked why.
Politics - I'd be curious to see if pedos tend to have different affiliations. It would make sense but I've never asked about this.
The last item - I don't think it's that bad and regardless, this possibility has never gotten me down. Of the few pedos I know who have come out to a lot of people in real life, the response is not negative the vast majority of the time - drawing on the cases I actually know about. It's different with strangers, but screw their ignorance and stupidity, let them stay stupid. Besides, think of the number of people who wouldn't like someone because of their race, wealth or poverty, and so on.
