We're well past identifying the source of the problem. If aliens invaded and everyone was debating how best to fight back, you'd be sitting there saying "Why is nobody blaming the aliens!?" Everyone who would understand that the country is falling into fascism already does. Anyone who doesn't simply hasn't yet admitted that they like fascism.
Yes, fascists exist, and are to blame for a large chunk of the failures of society. Now is the time to figure out who's going to help fight against them in a way that keeps them away for as long as possible, and who's going to claim that they had some good points, setting the stage for their expedited return.
