And "gay marriage" isn't an "important issue" either.
But the problem is that supporting gay marriage has cost the Dems severely. And if Republicans support ID, it will cost them too.
ID is a wedge issue, not in the way that the Discovery Institute intended (to wedge God into science classes, and from there into the rest of public schools). Instead it will become a political wedge, splitting up the Republican base. When schools do indeed "teach the controversy", ID has been documented to lose, thus there isn't even any gain for religious conservatives for the cost of spliting up the party.
A little experience around ID posts on FR should tell any Republican that this is not a good issue to bring up. There are more important things religious conservatives should concentrate on, such as the war against Christmas, and abortion. ID is a damaging distraction.
Now that the cat is out of the bag on the illusion of morality and ethics, how do we avoid the inevitable nihilism described above? I don't see how. Any variation from it seems to reveal an inconsistency in position.
Given that, I will ask the question I asked a while ago. Why do the atheist/evos care what is taught? Or care about anything for that matter? In that world view, all is vanity and anything that seems to matter is nothing more than "an illusion fobbed on us by our genes to get us to cooperate".
The only gay thing that is important is lesbians (and only if both chicks are hawt). Tee-hee :)
