You are not born gay, it's just the sin in you're heart, just like how many young men struggle with lust, or women with insecurity, you are born with it because the sin was passed down from you're father.
I was raised on this sentiment, that being gay is a sin. I'm also gay, so it was equally confusing when I was a kid. For the longest time I'd figured that I was either sick or that I just didn't believe in God enough, and to be openly about it, I tried to pray the gay away pretty often. Everything that I was brought up on was telling me that there was something wrong with me and I just wanted to be normal like other kids. This just made me resent other gay people and some of that resentment still exists.
I thought if people knew this about me, that they would hate me or think there was something wrong with me, or that they would hurt me. Along with that, I thought that if my parents knew, they would disown me and hate me. This really forgeted me up the most, and it was hard making friends with people while subsequently being afraid of them.
I don't have proof beyond word of mouth, but I'm pretty sure people are born gay. I honestly want to know how to stop being gay, or a lustful sinner, or whatever the forget. I didn't want to be some kinda freak and I really didn't have any sort of choice. I don't mean to antagonize you, but this whole belief ruined my childhood.
