If Jerry's stories are any indication, he thinks he's already won, it's just a matter of...doing the busywork of cleaning up. Everyone already agrees with making Jerry emperor of the world, they just...don't want to admit it because they've been brainwashed. But not so brainwashed they don't believe it, they just don't think they believe it. Or something.
I have to wonder how Jerry would respond if he actually thought there was a problem that required overcoming. What if the racists outnumbered the non-racists, and would win if a war broke out? Then you'd need to worry about convincing people, or using strategy, or something. But, of course, the question is the same even in Jerry's current world. If you want to do activism, why don't you actually...do it? Instead of devoting thousands of hours into claiming victory.
