I don’t understand what it’s going to take for someone to do something

Who is someone? Who is something? Organize and mobilize. I know all Americans didn’t choose this, but you’ll need a lot of support/like minded folks (which it sounds like you have). Trump’s shock doctrine has clearly worked. Try and focus on tangible steps to take whether it’s annoying the heck out of your elected officials, joining a grassroots org, or attending a public rally on an off day.
