I don’t think Trump is a social conservative in the normal sense.
He hasn’t promised to overturn homosexual marriage, he promised to defend freedom of religion. That’s a rather narrow promise if you think about it, but its better than the status quo.
It is on the basis of that promise that Christians decided to back him.

OK, so, if a gay couple sues a bakery (or any business) for refusing to service a gay wedding ceremony from now on (as they did with Sweet Melissa Cakes, which went bankrupt as a result of their losing the lawsuit), what will happen in a Trump administration?
