Just ask why he's being an ignorant asshole. Say, "hey, why do you think this or that." Bring up his stupid little journal on the Internet and tell him to stop coming to false conclusions. Tell him he's overreacting and being a drama queen.
I like entensity.net as well. My roommate actually started going there after I went to it because of the pure entertainment value from the site. Sure, it looks like a porn site, but it's really a Internet stupidity database.
Seriously...he's being an ignorant drama queen, so tell him. You may have a hard time confronting people but you'll feel better after you do.
