Also, if you are putting all of your energy into telling people that the election is rigged and the candidate is unelectable and your vote doesn’t matter? It doesn’t matter if that particular moron is “just venting” and still plan to vote. You are actively discouraging others from voting.
And those tend to be the same kind of idiots who think you vote once every four years. Rather than every single year. Because your representatives in congress matter a lot. So does the god damned local comptroller in your town. Because “grass roots” is not a bunch of people online deciding they like the c-span meme guy. “Grass roots” is about shifting your local party in the direction you want so that you can get those good candidates in office and turn a red state blue and so forth.
