The guy on the bottom panel is Jon Jafari who runs the YouTube channel "jontron" a couple years ago he went down the alt-rught rabbit hole, said some yikes stuff on twitter and ended up doing a long debate with another youtuber called destiny because of some comments he made in response to Steve King talking about immigrants.
On this debate he ended up digging himself deeper, bringing up the white genocide/great replacement conspiracy. Saying the most well off black man is still more likely to be a criminal than the poorest white man, claimed we've ended discrimination in the west, courts don't treat minorities differently, Mexicans are trying to retake American land, and that Irish and Italians were never discriminated against because they were always considered white.
It was a very much trump style rambling incoherent rant that kind of just showed he doesn't really have a defined set of beliefs but had just been caught up in the right wing disinformation machine. I personally wouldn't call him a white supremacist, but he certainly believes a lot of the same stuff as they do.
