Marlin,
Sorry for the delayed response, but your factual distortions actually made my mouse freeze up this morning, heh.
I am aware of the ridiculous incarceration rate in this country, including that 14 percent of our prison population is in for non-violent drug offenses. I think the problem is vastly exacerbated by our useless, counterproductive war on drugs and the power of the prison unions and other "prison industrual complex" stakeholders. But more to the point, your suggestion that low crime rate is merely a function of high incarceration is not supported by the wider facts. Crime rates in other first world countries has also been falling along similar lines as ours, but without the vast increase in incarceration. Correlation-Causation fallacy.
As for the PC thing: no one here is censoring you or dismissing you from the conversation. Words mean things, and context matters, so if you make what appear to be broad generalizations and animal metaphors but only about certain groups, then some people are naturally going to make assumptions about your biases. Feel free to continue to use them, by all means. But pointing out that people will look askance at your word choice is hardly excessive PCness. And yes, this is a democratic republic, with a constitution and legal traditions that pretty clearly limit the "tyranny of the majority." I don't know what your democratic majority rule allusion has to do with this discussion. I don't recall anyone here advocating for a law saying you can't call the handicapped "retards" or whatever you like, and I will continue to interpret you words as seems appropriate to their meaning and usage.
Foreign aid outside of Afghanistan and Iraq represents less than 1% of our budget, about .6% iirc. It's not there just because we love them foreigners, but to provide us with access and influence over their policies. We do, in fact get such influence from it. I don't have some sort of gigantic opposition to reducing foreign aid as part of a larger economic strategy, but don't decieve yourself into thinking that it will make a big savings or that doing so will be without foriegn policy consequences.
Immigrants and taxes, interesting reading.
