We can easily see the road that we are headed down. Anyone who views homosexuality as sinful or perverted behavior will be termed as homophobic, mentally ill, bigoted, etc. It's already happening in other nations. Members of the clergy are being arrested for speaking of homosexuality when they do their sermons. It will come to that here. We are well on our way now.
Good model of this is Canada, PC out of control
The MSM, the Hollyweird gang, and the chattering class in Georgetown, San Francisco, and Manhattan are dominated by pro-homo views. Other than that, the overwhelming majority of Americans either don't condone it or believe homos should STFU about it and keep it in the bedroom/closet rather than a public agenda.
The chances of being arrested in this country for speaking against homosexuality are nil and none. Unlike other countries, we have the First Amendment. Counting Alito, at least 6 members of the U.S. Supremes would never vote to uphold a law curtailing speech about homosexuality. If Ginsberg and Stephens are replaced in the next couple of years, you can increase that total to 8 (Souter will vote for his fellow pillow-biters all the time).
What are the odds of such a law being passed on a national level? Zip. Maybe 50 in the House and 10 in the Senate would support it...and then one would have to wait for a President Hillary to sign it ('09 or later). Assuming passed, the U.S. Supremes would promptly strike it down per above.
What about state laws? One could see a few blue states trying to pass such a law (California, Mass., Vermont, etc.). But public support in those states for civil unions/marriages as 'equal rights' is far different than public support for censuring/prosecuting heteros for speech. Doubtful such would pass...and if it did, the state laws would be stricken by the U.S. Supremes too on First Amendment grounds.
Hate to tell you this it's already happening here, too. Here is a Washgington Post article Psychiatry Ponders Whether Extreme Bias Can Be an Illness. There is a movement afoot to make 'homophobia' an official mental illness by inclusion of it in DSM IV, the diagnostic manual for shrinks.
We become more and more like the Soviet Union with each passing day.
