Some people suggest that you should just, in the interest of courtesy or social concord, keep your mouth shut outside of church or the home. During the 19th century, there was a similar movement promising liberation for Jews in central Europe: the slogan was 'be a Jew at home, and a man in the street.' The problem was that this solidified the opinion that only non-Jewish values were legitimate in the 'man in the street,' while undercutting the separate place in which Jews had been allowed to exist as a separate minority.
There's another problem, which is that sometimes one must engage the public discourse.
Gordon College students are banned from tutoring public-school students, because of the college’s embrace of standard orthodox Christian rules (no sex outside of marriage between a man and a woman); the request of its college president for a religious exemption from President Obama has now triggered a possible threat to its accreditation.The public school case is interesting. Because of the establishment clause, no public school teacher would be permitted to make the argument that their parent's values are just ordinary religious values of longstanding and with significant philosophical underpinnings.

In Lafayette, Calif., parents of 14-year-old public-school students are suing because their children were asked in English class whether their parents would embrace them if they were gay — and then these Christian students were publicly shamed and humiliated when they supported their parents’ values....
Note the similar strategies here: invite or force public comment and then discipline those who say the “wrong” thing.
Somehow an important part of the First Amendment's intent, that of protecting religious dissent, has become perverted. We may now suppress religious dissent, while still permitting mockery of that dissent, so long as we do the mocking from a non-religious perspective. That's handicapping the fight, and in a way that the Founders did not at all intend.
