If you are referring to the women's march on Washington DC back in 2016, that was a joke. The leader, Linda Sarsour, is a big time advocate of Sharia Law. Islamic women are beaten, abused, tortured, and executed under Sharia law. It is disgraceful that a movement for women's rights chose such a person to be their leader.
Another way to end racism would be by creating a unified mindset. Calling Americans Americans would be a start. It would be hard for groups to say the other has it better when everyone is American instead of pale or brown. But politicians care more about their votes gained by virtue signaling than they do national unity. So they will continue to divide Americans into minorities and communities based on skin color. When I see a brown person, I don't see a minority, I see an American. When I see a pale person, I don't see a majority, I see an American.
And don't misunderstand me, I am not saying blm is making things worse, I am blaming the politicians who piggy back on the people's desire for justice and equality.
