First of all, I can't help but think there's more dignity in not responding directly to this. I think even asking him to get into this is basically asking that he lower himself to the level of a guest on Jerry Springer. I think it's unjust to expect someone to descend to that level or be judged guilty which appears to be the standard you're setting.
Secondly, as the article explained, we've got a very big contradiction in the reason why Maya was kicked out and she can't really explain it away. If she was cut off because she was a homosexual, then why did she stay in her dad's Chicago apartment until after she participated in the counter-inaugural.
Simply put, the lack of context itself and the fact we're dealing with a family dispute casts a shadow over anything we're hearing from Maya or the Press. Frankly, it's really only God's to judge.
In the end, it could be that Keyes could have done more or done better as a parent. It could be there are some issues we don't know about, but that's it, we have one side on the issue and both sides will be colored by their pain and their feelings.
I think he DOES owe us an explanation. First, he is a leader and secondly, he's always said, yes stated that he would not remain silent on matters that are important. The situation with his daughter is importantant. The man has staked a claim in absolutes. If you absolutely do something, the absolute result will occur. There is a problem with his daughter that the absolute inputs did not equal the absolute outputs. If you believe as does Alan that Maya's sexuality is simply a matter of choice, then some input was faulty. If the equation of absolutes is in fact valid, then some input was in error. If the faulty input is not discovered to show and teach people not to repeat it, then Alan has missed the mark then he has so often stated that he will not remain silent with regard to matters of importance.
I agree, besides there aren't many people who have more of a reputation for contentiousness than "daughter."
