In a move most people consider 'shocking', Houston Mayor Annise Parker has subpoenaed not only sermons delivered by multiple Churches in the area, but also "all speeches, presentations, discussions, texts, emails, literature, packets, memos that had to deal in any way with homosexuality, or gender identity prepared by, delivered by, revised by, or approved by you or in your possession,” according to the Houston Chronicle. The mayor stands by her decision, her aide re-affirming that anything proclaiming that homosexuality is a sin preached by a pastor at a Church is not protected speech....."“The pastors made their sermons relevant to the case by using the pulpit to do political organizing,” Evans said in her statement. “This included encouraging congregation members to sign petitions and help gather signatures for equal rights ordinance foes. The issue is whether they were speaking from the pulpit for the purpose of politics. If so, it is not protected speech.”

and here is some fact checking The city of Houston, Texas, subpoenaed several pastors' sermons as part of a crackdown on preaching against homosexuality.
So basically, the government can tell religions and pastors not only what is a sin and what isn't a sin, but that they are breaking the new law by saying certain things are sins, breaking the new law by preaching the Bible, and the government will not allow religion to preach anything concerning the issue of homosexuality, unless it is positive.
I say, people who believe in the principle and regularly say 'but, Separation of Church and State! should be saying it the loudest right now. This is clearly violating the Freedom of Religion as well as the Freedom of Speech.
