I mean I've literally had conversations with people on this board who think Germans needs to be suppressed because of what Nazi Germany did. If that's not trying to impose a life of guilt based on one's tribe, guilt would have lost its meaning. Generally political activists (just using this as a referent since we should all know what this means) believe in some sense of responsibility for mending the ills of the past (institutionalized racism), and that this responsibility is heavier due to the person's race (a white person has more responsibility for making life better for black people), and that the race of the person in fact determines how responsible they are, given racial privilege means power and therefore responsibility. There's also plenty of emotionality involved in this school of thought - the shaming and condescending tone of which should be very obvious. Again, if this isn't some sense of racial guilt, the general definitions of guilt should be re-written.
