I think it's satire. Between the oddly sketchy list of "suspect" bands and the lyrics telling men to get down on their knees, I sense some leg-pulling.

I looked at the site, and I'm not convinced it's sincere, either. The design is too clean (and the code comments are too conversational and knowing about web standards and the like) to feel like a true amateur job. The clumsy homophobia of the song lyrics don't fit with the professional site at all. The random capitalization feels like literate people trying to disguise themselves.

They even quote from Rabbi Hillel on this page.

The full Hillel quote and more:

If I am not for myself, then who will be for me? And when I am for myself, what am I? And if not now, when? (Pirkei Avot 1:14)

That which is hateful to you, do not do to your fellow. That is the whole Torah; the rest is the explanation; go and learn. (Babylonian Talmud, tractate Shabbat 31a. See the ethic of reciprocity or "The Golden rule")
