>What you are saying is word for word the libertarian argument against the civil rights act ("if we have to bake a cake for gay weddings, what if wants a cake for their child bride!"). I happen to disagree with it as it applies in the real world

No. I'm not. Please don't put words in my mouth.

I'll try to boil it down to as few words as possible:

If the government can take away your rights, then they can take away mine too. I don't support that and will defend your rights as vigorously as my own, whether I agree with you or not.

As for the example you give, bakers don't have to bake a cake for gay weddings.
