To come to the conclusion that all they learned from their Professors, Parents, Ministers and Rabbi's in the political arena was not based on Aristotelian Logic but may be bunk and that is to hard to handle...
My own experiences of politely handing them things we deem as truth, does not invoke anger but blanks stares. For instance, post the Colimbine Attack I am at a function with a table of liberals some of which were spouting gun control. When I asked them if they remember Pat Buchanan's 92' speech that this was a war on our culture, I said I am not sticking up fo Pat, but does anyone get his speech now? That what these two Evil Teenagers did, could have been done by any means other than a gun and what in the culture allowed this? Their was no retort, the blank stares and the silence was deafening.
Indeed. Timothy McVey used the more typical weapon of the terrorist, the bomb. It was well within these boys' capabilities of making an IED that would have killed many more people.
