Dunno if it celebrates it, but it's a world where people remove their limbs and even their faces along with large chunks of their skull to bolt on some mechanical parts. A tranny with a raging 10 inch boner is probably not high on the list of weird things.
As for the whole trans thing, I always find it weird how everyone kowtows to the whims of a subsection of a subsection of a miniscule percentage of the population. If I was a trans person I'd be ashamed to be associated with these twitter warriors and their constant whinging and whining.
