I get you on this. A lot of people really struggle to maintain empathy with people they may otherwise find despicable, but to me, increasing empathy in the world among and for literally everyone is a paramount goal. Take this example: A huge percentage of men who sexually assault children were sexually assaulted themselves as children. It's easy to dehumanize someone in this situation, but the reality is they have been both a victimizer and a victim in their lives. People are way more complex than our present instant judgment-based society allows for.
All that said, all Kyle Rittenhouse has to do is shut his ugly goddamn mouth if he wants to stop getting lambasted by the public.
