I still love you and accept that you were born this way, but you got it from your dad. His side of the family has the queer genes.
I think you're wrong. Are you having difficulties accepting your son or daughter's homosexuality?
Yes, it's not normal, it has to come from somewhere and it could be hereditary.
There is no evidence that homosexualiity is heredetery. You should accept your son the way he is. It's wrong to think hoosexuality is something bad.
