Tsk, I knew leaving those 14 year old newbs alive was gonna be bad for our reputation.
My good sir, if you base everything on what you see, then you're going to miss out on the undercurrents.
A good majority, including all of my fu-riends (kukuku) don't actually mention liking yaoi until I bring it up. There are only a few extremely vocal kids who squeal on about it forever, and they are usually the same age as twatlight fans.
Others prefer to keep their fantasies to themselves, their circles, and their doujinshi.
There are also a lot more yaoi (and yuri) fans than you would assume.
Also I love telling people I like yaoi because I'm me.
Sue me~
Oh and. Guro and vore are for those people who would've probably grown up to be serial rapists/killers if under the right conditions. But since they're not, they turn out to be pretty cool people. Really weird, but cool. I have a few friends like this, they're some of the most interesting people I've met.
Not a fan of those people who post their guro/vore art in places where the innocent can accidentally stumble on. Like dA. Get your own galleryplz.
