Does Chik-Fil-A actually practice anti-gay discrimination...?
Nope, not at all. The "problem" with Chick-fil-A is NOT it's actions, but the religious beliefs of the CEO...and for those religious beliefs the mayors of Chicago and Boston are trying to get Chik-fil-A run out of town.Actually, yes, the problem is Chik-fil-A's actions. It is not really important that the owner and board of Chik-fil-A is staunchly opposed to gay marriage. What is important is that Chik-fil-A donates a large amount of its profits to groups aimed at keeping gay marriage illegal, and continuing the nightmare of discrimination us gays have to suffer each and every day because 51% of the country thinks it's "icky."
This is little different, in my mind, from boycotting South Africa in the 1980s to show opposition to Apartheid. It may be a moral issue to you, but damnit, it's a moral issue to us too. Denying gays their rights is immoral. And increasingly, the public as a whole is coming to believe this.
