So I lose my right to free speech when I run a business. Oh, and my right to freely practice my faith?<quoted text>
That is free speech of individuals. The protesters are not refusing to provide service to anyone, because they are individuals who have chosen to avail themselves of their right to free speech and peaceable free assembly. It doesn't remotely correlate to a business, which is a place of public accommodation, denying service to a client.
What about no shoes, no shirt, no service?
It would be participating in a sacrilege to support a faux wedding as a Pastor.
