I've met a number of gay people, and none mistreated me that i recall.
The bible is clearly against LGBT practice in many places.
Of course, Jesus is clearly against fornication- which most straight people engage in.
It is important to be clear about what the bible says, but not cruel. It was Jesus who said to get the beam out of your eye to see the speck in another person's eye, and spared the adulteress being stoned.
Jesus sacrifice clears our sins if we believe, and the gift of the holy spirit and grace allow the blessed to become the new man and not behave as they would otherwise. Christianity says none can do it on their own.
Jesus said to love one another, and Paul said every virtue would be useless if he didn't have love.
the wage of sin is death, so to fail to inform on sin isn't love.
love is the key- god is love, after all
