"What do they think they will accomplish with their marches and protests?"

Perhaps you aren't aware of the role that public protest demonstrations played in advancing civil rights for black people in the US, in ending the US involvement in the Vietnam War, that helped bring women the right to vote, that pushed the awarding to gays of equal civil rights with heterosexuals, and brought justice and resolution to many other issues.

It you aren't aware of those things, you should be.

And now you are.
