I have noted before that for purely social interactions, age is a more powerful predictor of who I will choose to speak with than sex, race, perceived status, or other determinants. I give the example of attending my sons' soccer games decades ago. When I arrive, I am going to gravitate to the other dads, regardless of race or dress (though I may have wheels within wheels, certainly). I would say hello to the boys and there are occasions on which we would speak, even have animated conversations. The moms likely came next, and grandads, faculty if it was a school event, and female students would be progressively less likely. If I knew someone already they would cut the line.
But socialising is not our only activity. In particular, I am wondering whether there is a generational component to viewing the protests of the last year. The violent protests of the left were largely by young people. The violence-enabling protestors were older. I recall reading that a large portion of Antifa lived with their parents and were unemployed, but I don't know how reliable that is. It could just be some conservative partisan asking some people to fill out forms and making a few phone calls, calling that research. As many are college students and some advertise their unemployment and freedom to be at extended protests, it is at least partly true. Perhaps it is not fully relevant, except that many people on the right believe this to be true, that the protestors are young, don't work, have their needs attended to by others, and generally know little about life. They know what they have been told, and some of the young people are very good at picking up what they should believe. The thinking on the right is they blame others because they just don't understand how hard all this is. Putting up with bosses is difficult and infuriating at times. Creating wealth is not automatic, it is elusive, unpredictable, and labor-intensive. When one has responsibility for others - for spouses, for children, for other relatives; for employees, for community needs, church needs, neighbor needs - one has less interest in humanity as an abstract. (And less confident you can do much about that anyway.)
The DC protestors were older, and while few seemed to be wealthy, they did seem to be employed, with skin in the game about the country in general that was not purely hypothetical. To the young left, these look like people who have benefited from the system, and have some nice things. What right have they to complain when most things are already going their way? And now you want more? You are butthurt because your guy who is perpetuating all this unfairness you benefit from didn't get elected, and you want to throw your weight around to make sure the goodies keep coming your way. You just don't understand fairness, you don't understand justice. (You have stuff and I don't.) The young find authorities who are not young who tell them this - not incidentally, people from the A&H Tribe who also feel that society does not reward the correct people.
