To be clear, you're saying something akin to: bakeries and florists refusing to make wedding cakes (or arrangements) for gay couples? Good.
Facebook not giving unpleasant extremities a platform on which to peddle their beliefs? Bad.
Now, if you think the religious baker should be forced to make a cake? I disagree, but I at least applaud you for the consistency of your convictions. Note: "they should go to another baker" isn't any more applicable than "they should go to another web host/platform".
If however you do believe that Facebook should "have to respect free speech" of a political variety, but the bakery should have a religious exemption, I'll ask:
Why, when freedom of association (politics), political beliefs, and religious beliefs are all held on the same pedestal in the Constitution, why are you singling out only some?
And in either case, why do you feel an Executive Order by way of Presidential tantrum is an appropriate way to manage what is certainly a Constitutional legal principle, if not worthy of an Amendment?
