Viv,
Here we go again. Each time this topic comes up we get the same comments from the Libertarians and those who haven't realized that for decades the SCOTUS has interpreted laws based on the US Constitution, which is predicated on the common good for all, not special interest groups and with a clear delineation between church and state. And we say the same things. It may be grand in the Libertarian or Laissez faire utopian world some want to live in, but it isn't the reality of a constitutional democracy.
It's like wishing that Santa and the Easter Bunny were real instead of make believe. Wouldn't it be nice? Laws protecting minorities, women, the disabled, religious people and the LGBT community from discrimination make us better humans, give us better communities, a better country and a better planet. But the right wing, the X-tian fundies and the Libertarians will cloak their beliefs behind a fence made of hate.
