I write as a gay Christian about the tightrope between freedom of speech and religion and prejudice and discrimination.
One of the fundamental principles of Liberalism is to allow people to do as they wish provided it does not harm other people. When it comes to religion, what appears to be a simple enough principle becomes complicated.
Many religions, including Christianity, require its followers to proclaim “the good news” of their particular religion to non-believers. There are interpretations of many religions that say intimacy between same sex couples is wrong, indeed that any sex outside of a marriage between a man and a woman is sinful. The question then becomes, does proclaiming such ideas contravene the Liberal harm principle?
There are people who think religion is at least, mumbo jumbo, and at worst, damaging and divisive, and that whatever God, his Son or his prophets may or may not have said, it’s all nonsense, in which case, no harm done.
There are others who do have a faith, who are from sexually and gender diverse groups or who love those from such groups (family members, friends, allies), for whom it really matters what their religion says on these issues and who are seriously harmed by such declarations.
