[Lurking Libertarian]

We cannot/should not assign civil rights to behaviors

Religion is learned/chosen, not innate, but we provide civil rights protection against religious discrimination.

I think that what people do in the privacy of their own home is pretty much their business.

I don’t want the government (my tax dollars) used to SUPPORT what they do in their homes. I oppose gay marriage and gay civil unions because they put the power of government behind the gay lifestyle.

Religion is learned/chosen, not innate, but we provide civil rights protection against religious discrimination.

And that's part of the trouble with liberaltarians. They equate protecting religious freedom with protecting the license to bugger whoever you want. When the highest good and the greatest evil are considered equally worth of protection, expect your society to collapse.
