How do you figure that? Does the law say people HAVE to discriminate against anyone? I don't think so. Nor is it "endorsing religion", insofar as it is protecting the rights of ALL religions to choose associations, not just one.
It's endorsing religions specifically by selecting which religious beliefs will be exempt from the law - because certainly not any view that someone claims is religious will qualify. It endorses religious views in general by giving them special status above and beyond secular convictions. Why should a religious person be allowed to discriminate against gays because they believe God told them to, but a secular person can't do likewise if they happen to think homosexuality is an affront to evolution?
Dimwit, THE US CONSTITUTION gives religious beliefs special status. Do you now want to tell us that your extra-special, personal revelation that any thought anyone happens to pass through their minds at any given moment should be given the exact same weight should take precedent over the most basic, fundamental legal framework we have? Because the answer is going to be, "Shut the fuck up" if that's the case.
Well, if that's all you got...
As I said, I don't think intent of the first was to give religious views special status, but to prevent them from being specific targets. Many early Americans came here to escape religious persecution and they wanted to make sure it didn't happen again.
Sorry if that doesn't jibe with the hate-filled religiophobic world you'd like to live in, but . . . actually, I'm not sorry. I'm kinda glad it chafes your hide.
"Hate-filled, religiophobic" ?? Heh... seriously, you don't know me at all.
