If the fascists do outnumber you and like minded people who disagree with them, then sadly your views are just the minority, and there's nothing to do besides leave the country. But that is a strong claim, it requires that >50% of Americans are fascists or are neutral to them.
Not all citizens are brownshirts. The fascists are more mobilized. But they are, and always will be, a small minority. They might still dominate situations or periods, though.
