Troons, whilst in the throws of gender madness, perceive any warning or discussion of possible surgery complications as a narcissistic injury, since it's saying that the thing they want so badly isn't 100% good and perfect. This is also part of why they fly off the handle when real women talk about how having boobs and periods can be a painful nuisance sometimes. The afflicted troon needs everything to be either all good, or all bad. Taking everything personally and seeing the world in entirely black and white makes life hard for anyone, as does unnecessarily cutting off your junk. So you combine the two and it's just a nightmare.
