Because social movements are generally minorities calling them out on the system that was built to place white straight men above everyone else. They don't want to give up their privileged status.

The gay rights movement called them out when they were arresting people for being gay. White tears were shed.

The civil right movement called them out when they were passing laws to have black people legally subjugated. White tears were shed.

The feminist movement called them out when women were being treated as second class and subject to legal discrimination. White tears were shed.

The immigration reform movement called them out on racist and POC hating policies, as well as racial profiling. White tears were shed.

The only thing they can empathize with is simply the white tears and not the humanity and concerns of minorities.
