Let's say being gay is a choice

For the sake of this arguement, let's just say that people choose to be gay.

Currently Texas is poised to be the 19th state to pass a state constitutoinal amendment to ban gay marraige. In Main, a conservative group is urging people to quash a new law prohibiting descrimination based on sexual preference. Meaning, of course, that they want to descriminate against people based solely on the fact that they are gay.

Now, let's say that being gay is a choice, and that's why they are against gay marraiges and gays in general, that because it's achoice there's no inherent right to it, but isn't religion a choice?

No one is born Catholic, no one is born a Christian, or Jew, or Muslim. Even if they are born into a family thereof and raised in a society that heavily promotes a certain religion, people still choose to be of one religion or another.

So why can't I descriminate against people based on religious choice?

Some religions accept homosexuality, Protestants for one. So can I then descriminate against Protestants because they accept gays, and that's against my religion? If I can descriminate against gays, can't I descriminate against religions that accept gays?

This isn't even a slippery slope, people, it's a sheer cliff dropping off into the void.

The United States Constitution is inclusive, not exclusive. It's designed to include people, not exclude them. It's designed to accept people, not descriminate agaisnt them. One person's religious freedom does not trump another person's religious freedom, and yet that's exactly what we're looking at with this.
