No, I have not seen millions of people unleashing chaos on the nation. I have seen some pockets of disturbing actions, some of them you have listed. I hate trump, but saying every single person that voted for him (+30 million more) are evil and brainwashed is not something I agree with.
As for Rittenhouse, no I don't think he should be made an example of, but I also do not equate the two. One is a murderer of two people whose life is essentially over. Regardless of future rehabilitation there aren't many prospects for him. The other threatened a person they will never be able to harm, and should not have his entire life ruined over it. I would say the exact same about a kid that threatened trump. Both need removed from society to get professional mental help, and I bet neither really get what they need because most people in this country are only interested in punishments.
That's all I'll say as it's not really on topic, I am definitely more liberal about this stuff than most people.
