What religion are you?

[angus]

thus the the moniker has a lessor included category after the broader one.

It seems that your Greek is a little rusty, counselor.  The broader term would be the second one, etymologically speaking.

καθολικός.  It's a greek word that means "universal."  Comes from down+whole.  Cristian comes from Christ, which of course is the English version of Χριστός, "the anointed one."  Catholic, as an abstract concept, therefore, is a much broader one than Christian.

Also, the government of the PRC has five officially-sanctioned religions.  Protestant and Catholic are two of those five.  Being outside Western religion, they are perhaps more objective when it comes to its classification, their subjective classification of Falun gong as a threat notwithstanding.

I think "Christian" is more of a label identifying many religions, despite the dogma that we are taught (or not taught, depending upon your school districts over-reaction to supreme court decisions) in comparative religions classes in school.  I think you can argue that Catholic, Mormon, Jehovah's Witness, Calvinist, Rastafarianism, etc., really qualify as separate religions.  They vaguely resemble one another in creed, but in code and cult they differ markedly.  Moreover, even in creed there are some significant differences.  Some alternative philosophers have been writing about this for some time, and there's a significant body of literature that supports the idea that these disparate faiths united in the coinage "Christian" are really better viewed as unique religions.

In any case, taking a Kantian view, I will suggest that the OP probably meant to be inclusive, and not exclusive, in the voting options.  Y'all need to stop obsessing over the options and just pick one.
hhhh

I don't entirely disagree with you. I think agnosticism includes both theistic and atheistic options.

Moreover, atheism includes both religious and irreligious options.  There are the traditional religious atheists, who practice ancestor worship or animism and have been around as long as the polytheists and longer than the monotheists, and then there are the latter-day atheists who want to stamp out all religion, and whose brand of atheism is worn like a badge of honor and is proselytizing and evangelical and exceedingly annoying.  If I thought they'd show up at my door the way the Mormons and Jehovah's Witness do, with pamphlets and such, I think I'd nail it shut.
