We can fight for a better and more equitable future for everyone AND VOTE. This isn't an either/or, you need to do both. This isn't about idealism, it's about survival for a large amount of people. I get it, I don't love it either, but a good amount of life is choosing the lesser of two evils, there are no utopias. Maybe you're lucky, and come from a place of privilege, and Trump being President won't really effect you, but here's a group of people who will be affected:
Women
People of Color
Disabled
Children
Vets
LGBTQ+
Immigrants
Homeless
Poor People
