You’re right, even a letter from the fire breathing attorney’s at FFRF isn’t enough to get a teacher fired. The teacher’s union is quite powerful around here. So no teacher will be fired immediately (if ever) for answering a student’s question abut creation.
It is all public theater now. Look at the recent happening in Arizona. Both sides were fighting and in the end reason and the law prevailed.
To be clear, FFRF rarely goes after individual teachers, we go directly to the Superindent level. We try to keep the name of the teacher out of the public. But most of the time if a teacher or coach gets all Kim Davis on us “I am doing this on God’s authority” on us, we go right at them and demand that they be fired for having Kindergarten students color a “Jesus loves me” coloring book.
