You know it's really hard sometimes to put myself into in this case, your shoes, and look at those first two as making a political comment about race.
I guess to you it looks like the first is inventing the political lie that there are differences in intelligence between races?
When I read the first one, I see a joke about the fact that it's a taboo to talk about heritability of intelligence (despite that being by far the strongest predictor of intelligence, with heritability (parent IQ) being about a factor 6 stronger than schooling+wealth+adoptive parents combined). Whether that says something about race or not is a secondary point. It may be an inevitable conclusion that there are differences in averages when it is heritable as the data shows. Since in public discourse you can't mention anything besides sociocultural causes.
I guess when you look at the second one, you see racist comment about (supposedly) bad black owners?
When I see the second one, I see someone being a smartass and then inadvertantly saying something that would be regarded as racist, possibly rightly so.
I guess when you see the third comic, you see a head-nod to the fact that jet fuel can't melt steel beams and by extension, that 9/11 is a hoax.
When I see the third one, I see something like when 4chan autists got an AI chatbot to tweet that hitler got swag; in this case asking innocuous questions that would lead to an answer that should be censored.
Am I getting your perspective right? Do you get mine?
