The thing about those greentext stories from 4chan is that you've got to approach them with the assumption that the first person narrator telling the story is more or less a villain protagonist. This person turning out to be a good, wholesome person, or having their experiences change them into a better person, is a pleasant surprise, not something you should expect by default.
Whether this story they're telling is a work of pure fiction, or a harrowing tale shared as an anonymous confession of one's sins, it's safe to assume that it was written by a sad, strange little man with several things wrong with him.
Like I recall stumbling upon one where OP starts his post by saying that his favourite things in life are smoking meth and jacking off to gay porn. He's also gay when he is not on meth but anyway that's how he rolls. So he's in the middle of a completely normal afternoon, 10 hours in on a porn-and-amphetamine binge, when he suddenly regains self-awareness and finds himself jerking it to fat transgender femboys on tumblr.
So he steps back to consider the situation, and comes to realise that either he has to reassess his perception of himself, or his perception of the world around him, and that he would rather completely shrug off his previous perceptions of transgender identities and accept that trans men are men, than spend even one minute doing any kind of introspection of himself or his own thoughts and feelings.
Content with this, he carries on with frantically beating his meat to someone's fat tits.
