I'm not trying to describe the millions of people like you who have some tangential awareness of these activists and assume the best about their intentions. I'm speaking of the folks squarely within this belief system. Are they universally oriented towards self-obsession, authoritarianism and perpetual victimhood? Of course not. I have dear friends who will express sympathies for the folks within this belief system and assume that these activists are, for example, just interested in achieving "equity" for oppressed peoples.
I don't argue that poor people are all looking for handouts. As a matter of fact, I often mention to students and adults like that many of the hardest-working folks I've known have been people who don't make much money. At times, you will hear me comment on the sloth of many of our wealthy folks, actually. I don't think that's a particularly good comparison.
I also don't think the comparison of white abolitionists or white civil rights activists in the past is a good one, either. It appears good superficially, but when you dig in to the belief system of the current crop, you recognize that the current folks have fundamentally different premises from which they operate. I've listed them many times and those dogmas sometimes run 100% counter to the folks from the past you mention.
