Personally, I had to get tagged for the sake of family. Or in this case, access to a hospital during their cancer treatment. Which failed BTW seeing how Big Pharma cares far more about profit than effectiveness. And who is it again that was in charge of "the cure"?
From personal experience, the ones who got tagged honestly believe that they've done the right thing and anyone who tries to sway them from their righteous path is an enemy. I'm witnessing religious fanaticism over something that was overblown by the media of all things. Considering that there is an equal amount of people who personally got burned by this new religious awakening ala Summer of love, there is an equal if not greater amount of people who simply aren't buying this new communion.
And if history shows to what happens when you put two religious fanatics with differing dogmas together in a room, it turns ugly. This is part of the reason why I feel there is a much bigger powder keg now than it was 2 years ago. And trying to sway a religious fanatic from their faith is a tricky problem. And a good chunk of kids have been indoctrinated into this quasi-relgion.
