Both you and the person you are quoting misunderstand what fascism is and does.

Just because fascists are less free marketeers than neoliberals don't make them anti-capitalists.

You CANOT pit fascists and neoliberals against each others, they systematically work and develop together. Just look at how much liberal countries tend to be passive or even openly protective toward fascists. Have y'all already forgotten the openly swastika wearing neo nazi gang that did a demonstration in some big city in the US just last year and how both the police and the state did literally nothing about it? Just look at how historical examples of fascism came to power and at who supported them, spoiler, it's all capitalists who helped them coup their government and willingly collaborated with them.

Yes, fascists do sometime say that they are not capitalists and critic capitalism, but if you look at their acts instead of their words you quickly understand that it's all rhetoric to appeal to the public and that they are in fact pro capitalist.

And yes, those "concetration of economic power" absolutely do care about ideology, more specifically, they want a pro capitalist ideology to dominate and they want it to be as favorable to their rate of profit as possible. Again, look who supported Hitler and Mussolini since even before they came to power, look at who supported and helped to power Augusto Pinochet.

And no, aesthetic is far from enough to make any significant portion of the bourgeoisie switch from supporting fascism to opposing fascism.

It is not a 3 way tug war, fascists and neoliberals are very much in the same camp.

So the critique of Jon Steward of this farce is absolutely important but just as important is the prevention of the worst case outcome. Even if you believe that fascism is the inevitable outcome sooner or later, personally I believe later is better because it allows more groups of people time to prepare.

Electing Biden won't delay fascism. This dude has been rounding up migrants in literal concentration camps, has passively let the right repeal a bunch of minority rights even though he had more than enough power to stop it and has given his unconditional support to a literal apartheid state's genocide against their territory's native population. At this point, continuing to tell yourself that you are doing anything against the far right by voting for Biden is just self gaslighting.

Also, did y'all forget that Trump has been president before? We already have a good reference for what a Trump presidency would be like. Sure, he'll continue to make things worse for everyone but the millionaires and above but implement outright fascism? I doubt it.

He will certainly lay the ground for fascists to take over in the future, but that's only if push come to shove for them.

One thing you need to understand about fascism is that it is the capitalist's last defence against the threat of revolution. Fascists don't fully take over in time of mild crisis let alone in time of relative political stability like the US right now, they take over to crush popular revolutionary working class movements that all less extreme measures failed to stop. The US as of now isn't close to have such a revolutionary movement any time soon therefore the American bourgeois state has no reason to let the fascists take over so soon. In 1 or 2 decades from now this will most likely be different but for now I wouldn't bet on it.
