When I started chiropractic college chiropractors were, according to the AMA, an "unscientific cult". Heck, some essentially still say that (see my Blog entry on Katz and Dogma). Nevertheless, Sharon Begley's column in Newsweek points out that standard medical practice is often unscientific. Looks like the pot calling the kettle black.
But I figure a double standard is the norm, and just get over it.
