First of all, it's misleading in its categorization: "half of people who voted in the last election" is not the same as "half of all eligible voters".
Second of all, a lot of the people who voted for Trump do not meaningfully "want fascism". Some do—no question about that! And, unfortunately, some who didn't before have rationalized themselves into wanting it now in order to self-justify their decision to vote for him.
But many of them are low-information voters who genuinely do not understand what is going on, and fall into one (or more) of a few categories:
- People who have always voted Republican, because their parents always voted Republican, and that's just The Way Things Are.
- People who have been brainwashed by constant propaganda from Fox News over the past 30 years telling them that Democrats are Evil.
- People who have poor to no civics education, have seen their economic situation slide slowly downward over the last few decades (or fall off a cliff, eg in 2008), and have heard the various Republican candidates telling them, over and over, "Just vote for us! We will solve all your problems. You don't have to worry about how!" (or "...by punishing the evil Others who are the cause of every ill in this country", depending on how racist they're already primed to be)
None of that requires "wanting fascism". And I can tell you, from personal experience, that there are still people out there—left, right, and center—who genuinely do not know what is going on. They don't watch the news. They just try to get by. They have no idea that ICE is abducting citizens off the streets, that Trump has shattered the executive branch institutions that actually run this country, or that the Supreme Court has said that Trump can do whatever the hell he likes.
If you want to be able to fix a problem, you have to understand it in all its nuance, and just dismissing tens of millions of people as "eh, they all wanted fascism; guess there's no possible way to reach them, then" is the wrong problem definition.
Don't be absurd. Fascism rose in Germany, and was defeated. Fascism rose in Spain, and Italy, and was defeated.
We can defeat fascism too. We will defeat fascism too.
It'll just be harder if more people think like you.
