It depends whom you ask! There are certainly some people both off- and on-line who seem to think that uniformly slurring all white, male, cis-sexual, whatever folks as "oppressors" - and even occasionally suggesting, apparently as a serious political proposal, that "Whiteness" (whatever that means) is something that should be forcibly done away with - is an effective way of advocating for diversity.
I will say that I'm not on Facebook, Instagram, or tiktok though, so I might be missing a cultural moment.
I have seen people point out that the concept of "whiteness" has shifted over time, and doesn't really have an immutable meaning.
Maybe you could look it up instead of dismissing it out of hand

Feel free to disagree afterwards, but the words do have meaning. And not knowing them is not an argument against it.
"Ending whiteness" does not mean "killing all white people" or "eradicating all European cultures" or whatever the parent comment was implying. (Or am I reading too much into it?) Though perhaps you can find some moron calling for that on Twitter.
Or do you mean that sociologists who speak about "abolishing whiteness" secretly mean "abolishing the behavior and identity of white people"? No I wouldn't agree with that. I think they mean what they say, and when they tell you their definition of "whiteness", that's what they're referring to. Not some other thing.
