Religious freedom seems to be mostly about being able to discriminate against gays and deny women funding for contraception in health care plans. If those are the only areas in which people and institutions are not religiously "free," then I would say that religious freedom is fairly robust. The entire legacy of Christianity apparently depends on a few issues like this. It's not as though the Baptist mayor of a small town is shutting down the Methodist church. No, the entire issue is that religious institutions don't get to regulate other peoples' (non-members of the religion) sexuality. And now, apparently, they do get to do so.
It's rather strange because contraception is not a big issue in the Bible. Maybe Jehovah at one point didn't want Onan to pull out too soon, which he did so as not to impregnate his sister-in-law, but that's all I remember. Most churches don't force people to marry their dead brother's wife any more, so this might not be all that relevant.
