Personally, I just feel sad for them. I always call them whatever dumbass preferred pronouns or random trans name they want.
Of course there are only 2 genders, but I don't think its their fault that they have been lied too and confused into believing a man or woman can become a woman or man.
Pretty much all trans are just autists and retards that have been lied to and confused because of their low IQ. Most of them are victims.
It honestly is kind of sad when trans are depressed and think about ending their life. I wish we would get these people the real mental help they need instead of giving hormones and surgery.
