For the record, I generally side against people who claim religion as means to discriminate.

If you bake cakes, then bake cakes. If a gay couple wants a cake, who cares. All you're doing is baking a cake. Which is your job. You aren't being gay, you aren't endorsing gay-ness, you aren't offending god. All you're doing is baking a cake. Just like you do for everybody else who likes cake. So bake the damn cake and shut the fuck up.

But this goes beyond that. You're asking someone to crush the skull of a fetus and vacuum it's carcass into the garbage. How is the difference not obvious?

Baking a cake is not an act of gay-ness, so you can't claim anti-gay religious beliefs in order to avoid baking the cake.

But performing an abortion IS an act contrary religious beliefs. Huge difference. And the first amendment protects people's religious freedoms such that they shouldn't ever have to choose between keeping their job, and keeping their faith.
