Not quite, although to some they can be. See the answer below.
Sometimes it can be. Same as multiculturalism, sports, drinking, and many other things. Not necessarily in themselves, though, but they are definitely treated with the same fervour one can find in the newly converted by some of their... adherents, I guess.
I reject the dichotomy of "religion - science - politics - culture", though; I believe they all have an impact on one-another, regardless of how we feel about them.
That's probably worthy of its own thread, man. Suffice to say that there is often a blurry line and no clear-cut answer. Sometimes they just, well, are. I suppose it's the same way as someone with a foot fetish can tell 'good feet' from 'bad feet'. I have no idea since I don't share it, and they can't express it, other than they know and seem to agree on it.
I think the bottom line is that we have different personal definitions of "religion".
