He knew. He was ignoring it. I, for one, wrote him about it as I know others did too. One of his guests pointed it out on one of the shows where he was harping on it and he glossed over it. It didn't fit into his talking points I guess. I found it interesting that he was practically foaming at the mouth over this issue though. Made me wonder what personal nerve it had touched on and just WHY it made him so angry.
I used to watch him all the time but haven't since he blew up at Ann Coulter and refused to allow her to make her point. He is full of himself now and if he doesn't see the importance of Freedom of Association which is in our Constitution then he is not worth listening to. It is not the "whites" who are the major "racists" in this country and he shuts his eyes to that fact.
