Sorry for the double post, but I'm going to bed finally... it's way too late, but I wanted to finalize some things.
There are methods for dealing with these people. Saying there isn't is just blatant lies. Victims will get out, they will inform the police or authorities and they will take action. Sitting around in a circle saying, "There's this thing going on, but you'll never hear about it on the news." doesn't really do anything but spread fear.
The system will solve itself given time... just like most other things. People will be hurt by stupid people. It's a fact of life and building on my earlier point, it will die off as people become more educated and aware. The Internet has helped a lot of people and it will continue. The most important thing you can do it fight for the rights of speech and information. All forms... hate and fluffy.
You may think this is me turning a blind eye to the issue that is supposedly rampant, but I just accept that people will live the lives they want. They will make the choices they want and trying to enforce my ideals on them is useless. Utterly useless. Trying to save every person in every situation will only lead you to an early grave due to stress, anger, or flat out exhaustion. Sometimes you have to place a little trust in the established methods.
Unless you are willing to authorize door to door searches and violations of innocent people's rights, you simply have to wait for the cells to come active (and they will...) or you have to pay people to infiltrate all the religious organizations all over the country and try to find that "needle" in the haystack. Even if you do find that needle, you need to be ready for a Waco because they may not want you in their lives... and you need to accept that fact even if you don't agree.
Good night.
