Free speech: gay wedding cake and Resort for White Nationalists

Someone wrote a LTE comparing the case where a Colorado Springs resort cancelled the White Nationalist convention and the case where Colorado's anti-discrimination law forces a wedding cake business to sell to gays.

The letter writer argues that both cases are the same and:
"Why should a business have the right to deny service to someone just because they do not agree with the business owner’s beliefs or values?"

Of course the Colorado law doesn't specifically protect White Nationalists so the letter writer doesn't really understand the situation. If the letter writer was making a moral case, then should we be more subjective rather than objective?

The Gay wedding case involves love while the White Nationalists involve hate. Oh yes, they could argue that White Nationalists love themselves.

The problem boils down to the Bible which is the "official" arbitreur of morality. Interpretations of the Bible give it a definite bias against gays. Yet the Bible doesn't really allow anyone to disobey the golden rule. People wrongly pick and choose which part of the Bible to obey. Even Trump's love of Nazis demonstrates how he doesn't understand the basic idea: love trumps hate.
