My Boyfriend Hates Fat People, Including My Friends?

I know this isn't what you want to hear, but honestly, this guy sounds not just creepy, but thinking a whole group of people should be killed by gas chambers? My honest advice, is to not just break up with him, but do it right away and cut him off completely. Try to do it as nicely as possible so as not to make him mad at you, because just from your description of this guy, he sounds like someone who might fly into a rage and hurt any girls he dates. Ask some close friends (thin ones, so that they aren't hurt by his opinion of fat people) for advice on how to break up with him safely. Honestly, to use his phrase if I were you I would not "want to associate myself with someone" who thinks along the same lines as Hitler, and would like to see a whole group of people KILLED. Even if he is joking (sort of joking, as in he would never kill anyone) his attitude is as bad as that of someone who is really racist. This guy is a bigot at best. Don't worry about patching it up with him, get out of the relationship! Okay, obviously, I can't tell you what to do, but I would very very strongly recommend you do this.
