My eyes hurt after reading that.

We're not talking about handed-ness.

Maybe this isn't landing with you because you live in a shithole country that's not America. But here, under the very first amendment, in the very first sentence of the Bill of Rights, citizens are guaranteed freedom of religion. They can believe, and practice whatever religion they want to. And by any legal standard or precedent, Christianity is a religion. And their stance against gay marriage is a legitimately held belief, whether gay people like it or not.

Their right to exercise that belief is an inalienable constitutional right. We dont' bend the rules for wedding cakes.

However there is nothing in the constitution that guarantees your right to be left handed.
