Given how much trolling we get here, OP, it would do a lot for your credibility if you were willing to approach us under your own name. For all we know, with the way your questions are phrased, you could easily be one of our regular bullies looking to stir up wank here now that everyone has blocked you on tumblr. Personally, every time I've had someone approach me claiming to want to better understand, it's gone sour faster than you could say 'bad faith'.
In the meantime, a couple of things that might help you better come to grips with what we do here:
1) The Hydra Trash Meme is not a unique place. Fandom kink memes have been around in this exact format for ages, and almost without exception they centre around sex and kink. If you can understand that huge numbers of people enjoy taboo, shocking, 'naughty' sexual fantasies - and that a lot of fandom infrastructure exists to let fans indulge those fantasies - then you're already most of the way to understanding the HTP.
2) If I want violence, I can turn on the TV. If I want to watch Bucky get non-sexually tortured, I can literally just play The Winter Soldier on my blu-ray and skip forward to the bank scene. Sex is generally far more taboo than violence in modern Western culture, and the places where violent sex is portrayed (notably mainstream men's pornography) tend to be the kind of creepy I don't enjoy. I'd rather make my own space with like-minded people - and a lot of others felt the same, and so this meme came into being.

I hope that helps.
