Religious RandomThot - Clean or Unclean?

I know i've often spoke of how the three main monotheistic faiths are essentially the same thing evolved in different cultures. All religion ultimately just wants you to be good and do good, and that's what should matter.
It just struck me last night though, (thinking about these things as you do), that there are some pretty peculiar contrasts in religion, and the one that floated through my mind was:

Isn't it funny how Islam and Judaism tell you to refrain from eating swine, because it is a dirty meat? I've never quite understood the repulsion to pigs myself because those childhood viewings of Babe obviously affected me deep down inside. Plus they are so cute!

On the other hand, in Hinduism, beef is not eaten because cows are revered as a symbol of the sanctity of life. Givers of milk and hide, toilers in the field, and naturally... pissers.
No, really. Cow urine has been said to have untold health properties, which is why a group of people thought it was a good idea to turn it into a soft drink. Cow-ca Cola "has immense potential to cure various diseases."
Funny - i would've thought it would have the opposite effect.
It remains to be seen if the director of said cow urine venture had accurately predicted the latest in health fads:

"It will be a revolution of sorts. The acceptance of cow urine as a potent medicine is increasing day by day and once it comes as a cold drink, its demand will definitely increase. It will prove and justify the high stature accorded to a cow in Indian culture."

Oh, it'll be a revolution alright.

I'm sure everyone was just WAITING for a cow piss soft drink before snapping it up.

Anyway, I digress. It's just funny that on the one hand you don't consume it because it's pure; and on the other you don't because it's unclean.
So i guess you should stay in the middle way... and only eat the sort-of-dirty-but-clean-enough foods in between.
