Best way to convince trannies to stop remains to be to remind them of TIME.
>TIME
It passes, quickly. The further into your 20s you get, the harder it is to reverse things.
>TIME
Most people get less attractive with time. For trannies, this affect is fare more noticable.
>TIME
You are alone, and will remain so. The only trannies to ever find relationships are the ones who either already looked so male/female prior to getting an op that they can pass, and that's with extensive resources and work that you likely don't have access to. They also lived a normal, fulfilling social life which you likely have not.
>TIME
As your looks continue to deteriorate, your routine to even look human gets harder and harder. You WILL eventually settle for a basic look, and you will look like shit. You will forever be known as "that tranny."
>TIME
You aren't living in a revolution. Yes, employers and the like are more forgiving and some people with visible tattoos and the like can even get excellent jobs now. But a hulking awkward tranny with poor social skills who likely can't present themselves? Career prospects are poor, which means finances are likely poor. You won't have the resources to maintain the look that you could never reach anyway.
>TIME
Your parents will die. Maybe they are cat-ladies, maybe your dad is a faggot, who knows. They will die, and your one potential source of unending, staunch support will die. Maybe they hate you because you're a tranny. Once they're gone, you can't go back and change your own mind.
>TIME
People will stop gushing over you. They won't shower you with love/support, and it'll be awkward if you are still acting like a teenage victim in your late 20s/early 30s. The mantle has been passed, and nobody cares about you.
>TIME
You will find something to take up your time, to distract you. Probably whinging about politics. You will "embrace" your failure, probably ironically assuming a self-insulting identity.
Time will do it.
