I have a personal reason to despise "If you support the right of people to perform a distasteful action, it must be because you want to do it yourself!" I am strongly against most anti-recreational drug laws, and believe they are unconstitutional. I do not use recreational drugs, with the possible exception of caffeine. However, I will admit that it's physical rather than moral reasons (I can't metabolize alcohol properly, I'm allergic to marijuana and cigarettes, although, in the case of the latter, I suspect it's something in the paper rather than the tobacco, because cigars and pipes don't make my eyes turn red and make me break out); as far as other drugs go, I had a habit of researching the heck out of anything before I tried it, which pretty much kept me away from most stuff except a few esoteric herbal concoctions which were mostly legal anyway (meaning that I could be arrested for using it, but probably not convicted).
Still, whenever I mention my support for legalization of drugs, what I get is, "You probably just want to get high!", when my support actually comes from more important principles (such as a belief in an inherent freedom of thought). Similarly, I followed the goings on at Waco during the Branch Davidians debacle very closely, not only because of freedom of religion issues, but because I was working in computer security at the time, and the government was trying to set precedents that could have had me thrown in jail, or at least confiscating all my property, without my committing any crimes or even intending to do so.
I am VERY, VERY worried about the Digital Millennium Copyright Act. Essentially, it takes the idea of "Fair Use" out of the hands of the courts, and into the hands of the copyright owner. And it's being adjudicated by judges who have ruled things like it's legal to put information in a book, but if you put the same information on a disk, it becomes a gun and is subject to arms limitation laws (I WISH I were kidding about that). So they just buy whatever Hollywood and the big music publishers tell them, and assume that a bunch of college professors have no idea what they're talking about in matters of science and engineering. Sigh.
