Personally I wouldn’t mind hem/here teaching the younger generation.
Keep in mind though that teaching the younger ones is an stressful and demanding thing to do.
And I can’t help wondering about the mental stability like the person in question has.

Undergoing a sex change isn’t the same thing as having a nose job or an organ transplant.
It isn’t something you do lightly.
So how mentally stable is this person?

I don’t mind the fact that hem/her had a sex change, but the question of the mental strength.
Though it teaches the kids directly or indirectly to be more tolerant and open minded (which is obviously a big plus),what’s really going on inside that persons head?

Ps: I wouldn’t call her a freak, just a little bit confused.
