Actually, I believe that there are a variety of ways to "cut to the chase'--as it were; some of which I know work, from personal experience. The whole frenetic effort by the left to force PC rules of engagement, reflects the fact that they have no rational or believable argument for many of their basic hypotheses. Take, for example, the suppression of the former vigorous nature/nurture debate--that is, over the respective roles of nature (genes) & nurture (individual experiences) in any individual's performance.
I have thrown the gauntlet down to the Left on this for 60 years. See a fairly recent example: Footnote On Absurd Egalitarian Compulsion. They have no answer on the subject but to shriek insult--not convincing once more Conservatives realize what has really been going on.
I will read it, and then I can discuss it with you. Not today probably, because I have work I ought to be doing. I'm currently taking a break for lunch, but after that I have to get back to what I was doing.
