Give me a break already the only one pushing the conspiracy angle is you. I've been in places that sell (presumably heterosexual) porn in the same way. When I was in high school we had a video store two blocks from my house that had almost nothing but crappy VHS tapes from the 80's, most of which no one has ever heard of or were so bad no one would watch them today (Unless you consider 'Attack of the Killer Tomatoes' and it's sequels real classics). At the back of the store there was a non-descript metal door labelled adult labelled in small lettering, "adults only." not surprisingly thats where most of the customers headed. A few of my more shameless friends decided to check it out shortly after they turned 18 and I can assure you they were selling what anyone with any common sense would think they sold in back (I have my doubts that would include you).
I later lived in another town that had a porn shop move in, people protested in front of the shop every day, some even resorted to vandalism and shooting out windows to make their point. The shop didn't last 4 months. Why is it so surprising that someone would put hide that sort of thing in the back, or that it would constitute the vast majority of their business? It's not like it takes a rocket scientist or the CIA to throw a few Oscar Wilde books out front.
I vaguely recall that one-year-old post to which you replied. The article that I derided as crap then, is still crap now.
