I hear you that it’s tiring and intimidating dealing with fascists. That said I don’t think it’s factual to say they only need to win once, and believing so creates a strategic disadvantage.
Factually, world war 2 is the classic example of fascists needing to win continually and being unable to do it. The Nazis had a good showing in an election, Hitler was made chancellor and then they used that foot in the door to take over the government and seize many countries. But they lost in the end, and that was a result of resistance, not just militarily but the sum of every individual act of opposition.
There’s a concept of anticipatory obedience. Corporations and local governments sometimes fell over themselves to do what they thought the fascist government would ask before the actual ask. Even if Trump seized power, that wouldn’t be the end. They need us to cooperate. And by resisting in a concrete way (not just #resist posting of course) we will stop fascism.
It’s never over. Fascism is destined to lose. It’s a question of how much suffering and injustice can we avoid by defeating it sooner.
And believing like they want us to believe, that it’s all over, is a strategic disadvantage. If we believe we’re beaten or that victory is impossible we’ll act that way. Believe that we can win, and spread that belief, and we’ll act that way.
Eugene Debs, the must successful American socialist candidate for president, was at one point running for office while in prison. Of course he lost so I can’t imagine it helped
