I was pleasantly surprised to see how rational most responses are on this thread.
What truly makes me shake my head is the absolute conviction that some people have that they would have "done and thought the right thing" as a young person, in the face of indoctrination and example set by every person they loved, admired, went to school with, socialized with, etc., etc. -- all without any consideration for the time and force of will it takes to actually swim upstream against that.
Frankly, the people we need to be most afraid of are the ones with that level of absolute conviction that everything they think is "right" and that anyone who thinks or ever thought otherwise are unredeemable. That's the first step to dehumanizing someone, and I think we all know what comes after that.
