He should be able to say whatever hate speak he wants to. I agree. He should NOT be able to funnel corporate profits to anti-human organizations.
If we're talking about the Family Research Council, I have to point out simply as a matter of fact that Chick-Fil-A isn't donating company profits to any sort of illegal organization. The FRC, as far as I know, operates within the bounds of the law, so the Cathys are technically within their rights to do this. Should they do this? That's a separate question. But donating money to the FRC is no less legal than publically saying what he thinks about gays.
