WLC: "You can't prove the negative"

[Fake Messiah]

Much as I hate to admit it, Craig is right on the self-contradiction thing.

Doesn't that prove then that omnipotent God doesn't exist because he is a contradiction because he would have to be able to create a rock that he can't lift?

Definitionally, there are no married bachelors. A polygamist looking for additional wives is not a bachelor, in any way shape or form ('bachelor' doesn't mean 'man who is looking for additional wives', it means 'unmarried man').

Also, your point regarding same sex marriage doesn't work, since Craig does acknowledge the legality of gay marriage (he objects to it on moral grounds). But even if that weren't the case, your point still wouldn't work, since Craig not acknowledging gay marriage wouldn't alter the fact that a married gay man is not a bachelor.

The principle of non-contradiction (that a thing cannot be itself and its opposite at the same time) is pretty well established. 'Married bachelor' is a contradiction in terms.

I don't know. You could always say that maybe in some Galaxy on some planet.

Or take the case that some people don't acknowledge marriage that is not in the church. For instance, when Roger Vadim married Brigitte Bardot they first had a civil marriage, and the Church one was supposed to be the next day, and therefore Bardot's father did not allow them to have sex on their "wedding" night (they were staying at his place) because he only considered Church marriage to be the real one. So you could say that Roger Vadim was married and a bachelor at the same time.
