I've only just gotten She Thinks my Spex are Sexy to download properly, and I haven't heard the new one yet, but otherwise I've listened to them all. I'm just inured to gross shit at this point, and while I'm enraged by stuff like uneducation, I find it truly cathartic to have the piss taken out of it. Seriously, that one left me feeling morally righteous and a lot better about some of the shit I saw in Crazy Fundie School.
If you ever do an episode about spit, though, I'll have to bow out. My being able to watch a BDSM slave lick a toilet in a documentary without flinching and while enjoying the disgust of others, but having to put my head on my desk and cover my ears during a video of a man spitting into a cup and drinking it again (I gagged writing that) was a source of endless amusement for my psych teacher. I don't know what it is, it's just POW straight to the heaves.
ETA: I swear to God, on every forum I've ever been on, it's been the absolute worst posts I make that break a new page. I don't know how to stop it.
