Seems to me that each of those candidates have completely disqualified themselves by participating in that forum.
It's clear none of them understand the separation of church and state.
They're wholly unfit to hold any kind of public office.
Even if it's "only" the school board.

This is how they take over local governments. They rally their minority, push a candidate and the majority of the community stay home and take a nap on the off year elections. This allows them to gain power and affect state elections and eventually federal, though more of the voters come out for those elections making hit harder for them to win. But they can do a lot of damage at the local and state level.

I would think that is exactly what an extremist Pastor would want to do if he could get away with it.
