I'm not deriving any arguments, I'm entirely in favor of legalizing marijuana. I just don't like most weed-smokers I've met. Yes, the indolent stereotype is far more prevalent, but I've not seen people who fit that description. Sometimes they're very involved and very clever people, but they're very up themselves about the fact that they smoke weed. Also, I didn't dismiss them all - I was well aware that it wouldn't be the responsible thing to do and I specifically phrased my statement to reflect that understanding.
Incidentally, I don't like dogs, theater people or folks who use text smileys and 'wayyyy' too many letters in words...
