Wow Soccer, I can't believe you're calling me "worthy reading."  But I do think the Torah comes from God (though it's not clear to me what I mean by that, precisely).

That said, AJ, I'm a huge fan of your writing at Esquire, but I do find this premise slightly offensive.  I know plenty of people who are really careful about not wearing shatnez--it's not like you discovered it.  As for the question of whether we should follow rules that don't seem to have any rhyme or reason--that's pretty simplistic, too.  If you're living by the terms of the Bible how about starting with the first commandment, "I am the Lord Your God, you shall have no other Gods before me."  If you go ahead and believe that one, it makes sense to check for Shatnez.  

I think the real question is, does it ever make sense to follow a bizarre tradition that you've never felt a connection to?  Because of course you follow bizarre traditions all the time.  When it's your birthday, do people bake you a cake and sing and put candles on the cake?  In some places they might think your friends were crazy, baking, singing and lighting things on fire, but because it's part of how you accept birthday celebrations, you're into it.  The same goes for Shatnez.  It may feel bizarre for you, but that's just because until now you've never been around people for whom it was important.
