If you're thinking of corporate activisty types, the sort of people who promote hamfisted "everyone with light skin has internalised racism" mandatory training, then I'd wager the "corporate" part has something to do with what you've observed. I would certainly call such people "aspiring-radical", and I might even call them tepidly left-wing (especially with respect to the US's Overton window), but I think "left-wing radical" might be a misnomer, since the radicality is unrelated to the left-wing nature. There are strong first-principles reasons to expect that this politics does a significant disservice to members of the groups it's nominally attempting to help (and that's before you factor in the backlash we're currently seeing).
But I've never found the "left-wing" / "right-wing" dichotomy to be helpful for anything other than identifying The Enemy™ (which I consider a generally counterproductive activity), so take what I say here with a pinch of salt.
