Utterly naive. Do you think that someone who believes he's going to get an eternal reward from the supreme being for killing his enemies gives a damn about politics? And then there's some issues like the Westboro Baptist Church that you wouldn't necessarily want to solve politically - I mean sure, we could politically repeal the First Amendment to take away their free speech, but that wouldn't be acceptable.
Do you really believe those people to be common among faiths? The WBC, for example, is a small time cult made entirely of Phelps family. They scream loudly, sure, but they aren't really an issue.
To continue with that example tied in with the first amendment, if there wasn't an idea of "inherent evil" associated with their views and we just let them scream their heads off but ignore them (as we pretty much already do), there would be no conflict with their right to free speech politically.
As for the rest of your posts, I don't really see theist groups gaining power because their beliefs went unchecked. Groups like the Taliban or Muslim Brotherhood gain power through military force or promises of economic benefit. The religion that ties them together is always secondary in their rise. Al pretty much expresses this in the above post; and far more eloquently.
You even say that your main goal is rationalist thought and that atheism is a simply a side view. I think it's possible to educate a generation of rationalists without forcing them to abandon their religious beliefs right away.
Perhaps they will come to your conclusion on God on their own, or maybe their children or grandchildren will. That is pretty much how we all got to this position. I doubt anybody here is in a third generation of atheism. If not your parents then your grandparents probably have at least some religiousness.
