Gryffindors are all about justice, bravery, and taking action, so they’d usually be the ones rallying people to their cause and standing on the front lines of protests. They take drastic action with hardly any regard for the consequences.

Ravenclaws believe knowledge is power, so they’re mainly the ones spreading information and awareness as much as they can. The more people know about an issue, the more likely they are to help, and that’s what Ravenclaws are trying to achieve.

Slytherins protect their own and are also ambitious, so they are most likely to form support groups and try to organize charities relating to their cause. Organizing charities or even just raising money for one that already exists can be pretty ambitious, but it’s one of the best ways to help people out.

Hufflepuffs believe in equality and are unafraid of toil, so they’re probably the ones calling people out on problematic behaviors and pointing out patterns of systematic injustice. They’ll give you the benefit of the doubt and be polite at first, but they’re not afraid to fight you if you disagree.
