Freedom of Preaching!?!

Randy Steele, the senior pastor of Southwest Christian Church, had the FBI after him because of a sermon he preached on abortion. It amazes me that Christian sermons which proclaim the Word of God against our cultural travesty are viewed as suspect when thousands of Muslim imams proclaim anti-American and Anti-Christian agendas from their pulpits without complaint. Is there no longer any freedom of the church from the state?
