Why not legalize prostitution?

Sex out of marriage isn't frowned upon as much as it used to be. However I still think alot of people would have problems with legalizing prosititution. Alot of unwelcome additions come with prostitution, one of the big ones being drugs. If it was legalized would that change? Maybe. Right now though it would just devalue whatever region it happened in.

Recently a "Spa" near where I live was shut down because it was a front for a brothel. When I read about it, I just shrugged and went huh, thats interesting. The other people in my community treated it much much worse though. The way they described it, you'd think that in the middle of the spa a gateway to hell had been opened. I'll never have a problem with it, but a good majority will.

Jam it back in, in the dark.
