I don't think they are losing their belief in the separation of church and state so much as the religious are becoming desperate as they see their numbers, at least in percentages of population, dwindle. As their desperation increases, they convince themselves that the separation of church ans state isn't all that important, not realizing that it is a reason they are free to practice their religion. They never experienced anything but religious freedom, and take it for granted.

@snytiger6 I agree that is a factor. Christians are starting to talk like martyrs even though they still clearly in the majority. But, they don't seem to appreciate that fact that if they can force their religion on others, it is only a matter of time before other religions will start to do the same thing by claiming the same right to do so.

It's selective ignorance.

In my experience pretty damn stupid…..

A significant fraction of Christians are catastrophically stupid. Just look at the number of shit-for-brains public school governors who try to foist Christianity onto the students.
