The parent repeats precisely the disinformation of a political party. That shows reading comprehension and some communication skills. If this was an English class, it might get a B if the assignment was about disinformation techniques.

But this is social science and we need to apply other cognitive skills, such as understanding empirical evidence, controls, and causal inference. Using those we could generate other hypotheses from factors more strongly correlated than the leading political party, such as funding, generations of systemic discrimination, government violence, or other causes.

Regarding political party, generally the better educated someone is, the more likely they are to be in the Blue party. The most highly educated institutions, including those of science, education, arts, etc., tend to be overwhelmingly Blue.
