1. Thanks for the citations, but who the hell are F. Roger Devlin and Brett Stevens, and why should anybody care? Their blogs seem to be on the fringe, and not something one would see in day-to-day politics. I'm not saying you don't have a point. Our society certainly has a few of these weird eggs, but there brand of "thinking" is generally viewed as abject ignorance by mainstream society, isn't it?
2. How would your policy of physical violence be any different, or less self-superior, than the kind of violence you believe this type of talk incites? I'm not trying to be snarky. It's just that enforcing a prescribed way of thinking via violence tends to have a lot of ill side effects that people don't take into consideration before heading down that slippery slope.
