I mean the second one is just objectively true, the black community tends to vote as a bloc while latine communities can vary in a variety of ways because they're basically as diverse as the rest of the US as a whole is. Even from within the same country of origin there can be significant splits in opinion, northern and southern mexicans pretty frequently vote for different parties, because northern mexicans tend to be from longer established communities and families while southern mexicans tend to be much more recent newcomers.

Meanwhile the split in the black community is mostly just some dudes who got sucked into the manosphere and literally everyone else facepalming at their bullshit.
