The culpas sub is an absolute mindfuck, what is utterly frightening in that sub is users encouraging others to distance themselves from friends who are clearly concerned.

Oh, whoa, I missed that part. I'll have to take another look, that is really weird and concerning.

There is an underlying manipulation to transgenderism (particularly with 'elders') that makes me deeply uncomfortable, like this is a long game to something else.

Agreed. Well, we know about one part of it: the money. There are vast sums of money to be made in the medical industry, at least in the U.S.; companies want people who will buy expensive drugs from them for years and years. We know about a second part of it as well: homophobia. A homophobic parent sees an opportunity to have, instead of a gay little boy, a "straight little girl," and homophobic cultures use transgender ideology as an excuse to wipe out or subdue their LGB populations. Beyond those motivations... I'm not sure. It's very cultlike.
