I once had an argument with a former co-worker who thought that the two terms were interchangeable.

Mark Steyn has a great article in the Jerusalem Post [relatively painless registration required] that recounts some rather outrageous violations of free speech in Canada and overseas regarding homosexuality. No, it's not the gays who are being muzzled, rather it is anyone opposed.

Whatever happened to "live and let live?" If I can live with the occasional rustle from the undergrowth as I'm strolling through a condom-strewn park or a come-hither look from George Michael in the men's room, why can't gays live with the occasional expression of disapproval?

Christian opponents of gay marriage oppose gay marriage, they don't oppose the right of gays to advocate it. But increasingly gays oppose the right of Christians to advocate their beliefs. Gay activists have figured that instead of trying to persuade people to change their opinions, it's easier just to get them banned.

Disturbing, but increasingly true. Much like campus speech codes have used "harassment" as a cover for stifiling non-PC speech.
