What I hate is intolerance. I am intolerant of intolerance.
No one is forcing anyone to marry gays or lesbians, but to say that it is a religious right to refuse to sell them a cake, flowers or a sandwich, that is not any crucial part of any religion.
The Bible says a lot of intolerant things, but it does not say that selling gays or lesbians flowers, cakes or sandwiches is a sin.
