people are just afraid of difference. honestly no where in the bible does it say you can't be gay or bi or anything it says he loves all his children the same and he wants the best for us but we need to be truthful and all that yadda yadda anyways, god doesn't hate gays, he does hate hate, hypocrites, liars, and all that and even then he forgives those who ask for it. so your mum's reasoning is totally wrong xd sorry love, i had to rant a bit but i hate it when people do that. if anything i accept you! stay amazing! ^-^
