I don’t think Donald Trump will try to take away LGBT rights but I don’t believe that he’ll let gays intimidate or force Christians to serve them. I think Trump would encourage them to found companies and businesses that cater to them and their tastes; disgusting as they are. Porn and sexually explicit material is available to any adult but no one is forced to partake of it. Why in the world would our government try to do so?
It’s the latter issue that Trump might be able to handle well. Allow religiously oriented organizations to choose their transaction partners without interference from civil rights legislation, because rights in heaven trump (pun unintended) those on earth.
