Whatever you do, don't let people tell you to "get over it."
Don't let them tell you that the election is over, and it's time to "move on."
When they say you're a "sore loser," don't listen.
Because that's not how this works. We don't elect people, give them the keys to the car, and then step away. It doesn't matter who won, we should never do that, although too often we do. Myself included. It is incumbent that we do exactly the opposite. Never forget: they work for us. And when they don't, it's important that we call them on it and demand better. We don't have to wait until we cast our ballot to do that.
So protest peacefully. Demand more of our free press. Ask them why they aren't covering what you see as important. Contact your representatives, even if it seems like there's not a chance they'll listen. Post stuff on Facebook and Twitter and be willing to lose friends who aren't willing to listen (just make sure you listen to them as well, and perhaps find points of agreement somewhere in the noise). Donate to causes that can help us fight back right now, like the ACLU.
It's important. All of it.
