Just for clarification's sake, Jefferson's "separation of church and state" was a letter to a baptist church explaining that the church need not fear the government's intrusion into their affairs (not vice-versa).  And church services at the time, preaching Christ, was held in, no less, the chambers of the US House of Representatives. (How far have we come?) 
The attorneys should add to the suit that the district did not provide a safe space where teachers and students could be isolated from any opinion or belief not their own.  Hey, good enough for college snowflakes, good enough for public school.

Be a victim and hope for a monetary reward you share with attorneys who earn a living looking for "victims."

There are two sides to the story, and may it be that Ms. Fisk may have been a provocateur?
