I've been wondering about this stuff for most of my life. Even though this is a comedy its clear that these are his opinions. Very refreshing to see another white person acknowledging this.
For example, even as an adolescent I was aware that, for some reasons, us whites need things like "right angles" (an angle of 90°).
Yes, I understand that its much easier and more effective to make sure that everything is square when building (everything else will then fit together) but...it goes beyond that. I even seen whites nearly flip out (near mental breakdown) when just 'looking' at objects which weren't built level and square.
I've never once seen this sort of behavior from non-whites.
I often purposely built things without measuring them because I wanted to fight against something inside my mind which was compelling me to use right angles, flush corners, level surfaces and measurements to 1/64 inch (lol).
