I don’t think his acting career has anything to do with it.
He did say he could be supportive of the constitutional amendment if it were passed, he did say marriage is a man and a woman. I do not believe he is promoting gay marriage with that stance, but is rather opposed to it.
He just doesn’t like the idea of a constitutional amendment because of federalism. Limited is best. He is sticking with his principles.
You keep saying he doesn't like the idea of a constitutional amendment, but this story says he is actually proposing a new, different 2 part amendment. As far as federalism, the 2nd part of this "new" amendment would actually BAR State judges from ruling on any state marriage laws. That goes directly against federalism, he is trying to impose federal will onto state judiciary.
BTW... I do not agree 100% with the original FMA because of the same reasons Fred originally stated, yet now he is going in the totally opposite direction.
On Free Republic Federalism is becoming FREDeralism and that seems to be OK by some here.
