I'm seeing people downvoting this, I suspect because "fascist" is an extremely strong and polarizing word. But c'mon, downvoters: Thiel is, in fact, literally arguing that democracy is bad because it gives people with critiques of capitalism a say in the way their country is run. Furthermore, by citing the 1920s specifically as the last good decade, he's arguing not against socialism as much as against mere limits on capitalism like we saw in the New Deal. Beyond that, he's specifically arguing that, as Monocasa says, giving women the right to vote was a bad idea because women as an entire voting bloc are more likely to want some measure of reform in capitalism.

Again, maybe you find Monocasa's language combative and unbecoming and it gives you the vapors. But Thiel is specifically arguing that democracy is bad because it can get in the way of capitalism, and it is not wild and crazy to describe that as a fundamentally fascist viewpoint.
