So your criteria for righteously refusing to provide service is whether the individual had any choice in the thing that is leading to the rejection. So, that would make it OK to refuse service to say Muslims?

My point here is not that Trump is a great guy and businesses should be forced to deal with him. Quite the contrary, if I had a business that interested him I would probably also like to refuse him service. But I am not a hypocrite, or I try not to be, so I do think the same freedom should apply to every business, for any reason, as opposed to everybody being forced to adopt the same morals as me.
