Homosexuality is normal, although it is not normative. Longshot's noting of lefties and redheads demonstrates the problem with your 50%=normal threshold, as would genius-level IQ, being very tall or very short, etc. All of those traits may fall out toward the edges of theor respective attribute bell curves, but they are nonetheless traits that can be readily encountered within the population at large.
As for religion, some condemn hemosexuality while others do not. There is certainly no hard and fast rule to affirm that homosexuality is a sin according to all religions. This week in Orlando, one of the largest Lutheran conventions is going to be busy debating whether gay churchmembers should be ordained. Hopefully the vote goes that way if it comes to a vote.
Your comment about slave ownership is instructive here. Owning slaves was something that was considered acceptable 200 years ago but today we can clearly see it is unjust and immoral. Hopefully it will not be too many generations from now when the majority of people see that condemnation of others based on sexuality is similarly unjust.
