No, that is actually quite rude.
People don't like the transgender thing
you call them transgender
A transgender.
Of course it is okay to be a lesbian if you are a transgender woman - being transgender doesn't dictate your sexuality, that is something separate. Your sexuality is not something you can control or that other people can control, if you are a woman and attracted to other women you're likely a lesbian.
It's okay but a lot of people will find it weird.
Being transgender wont make him any different that way. He's a 8yo with toys I imagine so the worst thing depends on the child, not whether he is transgender or not.
You call him a suitor or a boyfriend. If things get serious, you would call him a fiancé and then a husband.
Chirstians don't like the transgender thing
im gonna guess thats "boy parts". Transgender
No, obviously it's not okay to beat-up anyone no matter who they are.A transgender guy doesn't just 'identify' as a guy, he is a guy just like a cisgender guy.
there are many helplines, and for girls, as well. try googling "transgender helpline" if you'd like to see.
There is a song by Vanessa Paradis called Is It Okay If I Call You Mine. It has the stanza 'Is it okay if I call you mine. Just for a time?'
