Ignoring the fact that the term "cis man" is retarded since there are only men and women, allow me, a man, to support
@Jhonathan45's claims.
I'm a guy nearing my thirties that's tall and in shape. Got reasonably attractive once I lost the extra weight and grew my hair out. I'm happy with what I've achieved. I'm "happy in my own body", as you people call it.
Still, if I encountered the typical reincarnation scenario where you can ask things from a god, I'd restart my life as a beautiful girl.
Does this mean I'm repressing my inner woman? No. I simply find the female form more appealing, which is also why in games I create female characters to play as. After all, I'd rather spend hours staring at a girl's ass than a guy's.
It's basically a fetish. And I reckon that most trans women have a similar kind of fetish (can't speak for women since they have different issues). Just that they take it too far and try to make it reality, when in reality it's impossible. Not yet, at least.
Currently, a man (and women too, of course, but I'm choosing to tackle just one side for this) can go through all sorts of treatments and operations to achieve a passable female appearance, but it is yet impossible for that man to give birth. The DNA hasn't changed, either. It's only the outer shell that changed. Not to mention that hormone treatments tend to sterilise the patient. One essentially becomes a cripple.
Now, if technology gets to the point where you can get submerged into a special juice tank to sleep for a few weeks while your body is changed from one sex to the other at the atomic and DNA level, with internal organs and appearance changing to match? Sure. I'll try and see what it's like to be a woman. May alternate genders every few months, even. Sounds like fun.
So basically, I admire the female form and would prefer to have it, but, being a denizen of reality, I choose to do the most with what I have instead of living in delusion.
Understand that I'm against the normalisation of transitioning not because I don't understand it, but because I know too much about it and its consequences.
I may get banned for this, but if it saves just one person from the pain of realising too late that you've ruined your entire life, and that detransitioning barely helps at all, then go ahead and ban me.
