Collective Shout is sustained by a small number of Australian partners. These are not big groups, and would quickly pull funding under any sort of pressure.
Collective Shout has a deep history with Christofascism and TERFs, so highlighting those angles is the way to go to get them pariahed. Once CS is out of the picture, we can work on undoing the damage they did.
