Now you're equating violence and gambling to sex? Sounds like you're doing exactly what I described in my comment. Equating sexuality with filth and disease.

Yes, there will always be people who do their best to exploit base desires (especially in our current economic systems), that doesn't mean what they use to exploit people is inherently bad. Maybe if we stopped trying to hide sexuality under the carpet like dust bunnies when your mother-in-law visits it wouldn't be nearly as exploitable.
