Unfortunately, as long as they keep pushing for "religious liberty," they can keep indoctrinating gaining new followers.
The ironic thing is, the religious liberty we need isn't "protection from non-religious" but "protection from the religious."
There are still towns where you can get chased out or shunned for not being Christian.
Not that this is unique - any time religion and politics become synonymous (Middle East, for example) then you're gonna have any other religion (or lack thereof) be oppressed. I've yet to see it happen with paganism, but the potential is most definitely there.
Personally, I don't care what percentage of the populace is religious or not, I just want the freedom to practice my own personal delusions at home or with like-minded people without being harassed, so long as no one's civil liberties are violated by anyone's practice.
So please, let's keep improving education, even at the "cost" of religion declining.
