It's the same thing people do to justify the rampant homeless problem in the US. It's all about" compassion" and "understanding" because actually dealing with these people requires them to be put into an unpleasant and difficult situation. Being institutionalized sucks, and historically the conditions have been terrible, so instead of fixing the issue with mental institutions let's get rid of them entirely and hope the problem sorts itself out. If you think that's a terrible idea than you are just an uncaring asshole.
Shockingly tho, just leaving these problems just seems to make them worse! Who knew! Now all those troons you were being nice to and defending have all fucked up their bodies permanently, had a moment of clarity, and 41%ed themselves! You just lead someone with severe body image issues to suicide! How compassionate!
I have lost dozens of friends over this opinion but I don't really care. This troonery always ends tragically and I'd rather not be complicit for my own conscience.
