You can usually suss out the latter in how they treat marginalized people. Guilt totems you're constantly trying to suck up to make *yourself* feel better about your privilege or guilt, or full equal human beings who you want to help dismantle the structures that oppress them, because you care about justice and have compassion for them? People acting out of guilt don't think about the mechanics of justice and the particular context of situations, they just unthinkingly side with whoever they feel most guilty towards because it's still *all about them* because it's *all about assuaging their feelings of guilt*, not actual justice or compassion.
