A last-ditch attempt to turn back the tide:
"For one state lawmaker, it's a disturbing trend in public education: Tennessee middle school teachers attending seminars on how to teach about transgender people and a Massachusetts kindergarten class being taught about homosexuality.
State Rep. Stacey Campfield, a Knoxville Republican, has proposed legislation to forbid 'any instruction or materials discussing sexual orientation other than heterosexuality' in Tennessee elementary or middle schools.
'It's such a blatant attack on freedom of speech,' responded Marisa Richmond, president and lobbyist for the Tennessee Transgender Political Coalition. Advocates for gay and transgender rights say they have noticed an alarming trend of their own: an assault on their lifestyle, which has required them to raise their profile in Tennessee politics"

But if Christian pastors were allowed to go into all classrooms and preach the Bible message that homosexuality is an abomination to God, that would not be entitled to free speech protections, of course.
