My god it's the same argumentation they speak for the BLM movement. "so if a movement a form of justice because of the hate suffered of a determined group, then it means the rest doesn't matter" dumb take. It's not because only one is shown that it's only that one that matters. What happens is that these groups suffer discrimination for being "different" - LGBT, other ethnic group taking away white people, people with disabilities, among others. Literally it's not written that "just that only one matters".
