You're right that our political situation is frustrating. I feel it too, how many elections can we have where "this is the most important election of our lives"?
That said, I'd encourage you to have empathy for other people, and to consider the possibility that if someone doesn't agree with you, it may not be because they're unreasonable, but because they have different life experiences and perspective than you. If you take that approach you may find people more receptive to your position. (And may get something valuable from their perspective too)
