@black runner, You are right on both that such thoughts are voiced on here and that they are offensive, but you might be underestimating the number of adults who genuinely have similar kinds of questions and need an outlet to freely discuss them even if only to eventually arrive at the same viewpoints as those considered politically correct. You wouldn’t be so mad if your child wanted to know answers to such questions, would you? You would be compassionate and patient with them. Of course, there is a point beyond which you can’t change an adult person’s thinking, but on the other hand, it’s also easy to make someone dig their heels in simply because they are made to feel attacked and stupid for their thoughts. That’s just human nature. I’ll take your own example below to illustrate why these “idle conversations” are better had openly than suppressed.
On race and intelligence: Some of your examples are caricatures, but only partially so. We live in a society where certain types of questions are not investigated by the academic elite because no one respectable cares to know the answers to them, and further more, if anyone voices politically incorrect thoughts like “are there correlations between intelligence (however measured) and race?”, they get canceled (e.g., Nobel laureate James Watson). The reality is that we truly don’t know, and I mean exactly that, i.e., it is entirely possible even that black people are more intelligent than lighter skinned people, or the other way round, or that there is no statistically significant difference. We do know that there are differences in disease proneness and use those race-based factors in medical treatment for example. We also have empirical evidence that makes it not unreasonable to think that certain black people are more or less good at sports like running, swimming, etc. So why is it not possible that there are differences in traits considered more cerebral?
The answer is that it is possible but we as a society have chosen to believe in the equalness of humanity simply because the world is a happier place full of hope and potential for every person of every color. As a person of color, I too prefer this world view. But we pretend like that is not an adopted point of view, but is some kind of scientifically established ground truth. This collective pretense is not obvious to everyone and sometimes needs conversation and clarification, especially since most people are not statistically trained to disambiguate the effects of race, poverty, and historical subjugation on outcomes like crime and societal accomplishment.
You may disagree with my point of view of course. But do you find my thoughts offensive and me “seriously disturbing” as a person?
