Here you're talking about three things:
1) What happened that day.
2) Rosenbaum as a person.
3) Rittenhouse as a person.
When talking about Rosenbaum, you're talking about his crimes and you're tying that into what happened that day. When talking about Rittenhouse, you're describing his affiliating with a terrorist organization and use of a white supremacist symbol as "may have some shitty affiliations", and you're following it up with a but about how that doesn't impact what happened that day. You're downplaying Ritterhouse's cozying up with fascist terrorists, and you're treating the two people's personal lives outside of the incident in two completely different ways.
Combined with these particular comments:
As someone said, this "doesn't look good". However, over several days we have all the context we need. Your approach to this is really fecked up. You can try to do your spiel about how people can't handle looking at the evidence objectively, that it hurts their feelings, but I'm not talking about the evidence or the trial. I'm talking about you.
