I’ve always wondered (and may have even asked this question before at HA), is there an equivalent to this when it comes to being fervently anti-drugs? Have any hardcore drug warriors ever been exposed as secret drug users? Off the top of my head, I can only think of this one, but that guy was neither a politician, nor all that zealous a drug warrior. What’s the difference, then? Obviously, the major difference between homosexuality and drug use is that homosexuality is in-born, while drug use is a choice, but I’m not sure that difference alone explains why the phenomenon of self-loathing only happens with homosexuality.
UPDATE: In the comments, Troutski points out that Elvis was made an honorary narcotics enforcement official by Nixon. That also made me think of an obvious example of this, Rush Limbaugh, whose love of Oxycontin and frequent railing against druggies certainly qualifies.
