I continue to find it very difficult to point out the similarity and apparent shared roots between different oppressive behaviours, without implying that the circumstances are of equal badness.
A case that just came up was how anti-vegan rhetoric often functions similarly to bigoted rhetoric (eg. transmisia, racism, etc.), trying to frame everything as things "being taken away" from the privileged group.
Another example from a while ago would be the similarity in assumptions and behaviours between actual colonialism, and the way that (especially white liberal) Twitter users felt entitled to the entire fedi adjusting to their cultural expectations.
In both cases, the two things are obviously not of the same impact; but I do feel that calling out the similarity helps people to identify problematic patterns (and subtler forms of them) more broadly. But how do you communicate that without implying they are equally bad?
As a bit more background: the reason that I think it's important for people to learn to identify the more subtle variants is not just because of the harm caused by those variants directly; but because they can serve as fertile ground for the more problematic variants to persist and crop up again later. Kind of similar to how racism often starts with racist "jokes", not with overt rhetoric.
