Religion is the main reason for promiscuity being frowned upon; with that said, more people are religiously unaffiliated than ever, and the numbers are going to continue to grow with each generation. I feel like the majority of people do and accept, what they're told to do and accept. So if that government campaign did happen, it would be coupled with the non-religious movement, and I don't think it would take more than two decades to be normal, here in America.
As for people still not wanting it to be their kid, I agree. I just think that eventually having a child in the sex business, would be on the same level as having an adult, lazy, stoner for a kid. Sure, you go to sleep and wake up wishing that they to do better, but it's not the end of the world, and disowning them doesn't cross your mind. But once again, this is what I think would happen in America.
I know you're Brazilian, is it true that many of the sex workers there, are being put in English classes to better service the crowds for the world cup and olympics? Also, I'm curious about how you personally feel about women who prostitute themselves, to get through school, or to get the capital to start a business, or something like that. Do you look at them like they're dirty or less than, or as people who were willing to do what they felt they had to do, to make a better life for themselves and the ones they love?
