To carry off his own property, yes. But it's not required that someone take the class from that person.
Still and all, if the instructor agreed to teach it to all who came for it, he cannot fault the law for holding him to his agreement.
If he's willing to give up his certification to teach the class, however, I don't see that there's much else they can do to him.
Agreed! And nothing should be done to him.
In the meantime, while he is still licensed to teach the class, I wonder how he determines if a prospective attendee meets his requirements? Does he ask everyone if they voted for Obama and if they are Muslim or just those who fit the stereotype? I did not see where this was discussed, but I'm sure he would have no issues with that in the first place.
Most likely he was simply playing to his preferred audience to increase business. Now, Muslims and those who voted for Obama know they are not welcome. They will avoid his class, even if it were the only one that fit their schedule. His reputation will precede him and he will meet his goal of keeping certain individuals out. He can recant his statement and they say, "Hey, I welcome everyone and will be just as courteous to them as they are to me." I'm sure this could work in his favor. He may lose a few supporters, but for the most part all will be well.
