So where does the buck stop, LT? Should Christians have the right, based on religious belief, to refuse people all sorts of services? Should a Christian, if he saw fit, refuse me entry to a gig because I was a non believer? Is it okay for a Christian to refuse to let an unmarried couple with a kid into a theme park?
Also, plenty of scientists believe genetics have an important role to play in a persons sexuality also. You say there is no proof beyond reasonable doubt that people are gay as a right of birth, but the vice versa also applies. It's funny how you demand scientific proof for certain things, but it doesn't matter for others
