my issue is that liberals aren't going to resolve fascism because they create the material conditions for fascism.

fascism doesn't appear from nowhere, it emerges from the immiseration and instability that capitalism produces, something liberals are content to 'manage' without resolving.

oppose fascism mildly

What does this mean?

Because their opposition does not work.

Let's look at Germany, their favorite example. The liberal position was to compromise with the fascists, and attempt to put in Hindenberg as the stop gap. The problem was that Hindenberg was unwilling to EVER accept liberal or social democratic (SPD) government. And so when he couldn't find conservatives to keep power, he put the Nazis in power.

The "mild" opposition of liberals is only for fascism - they're very good at holding down the left while they let the fascists take power, and that's exactly the problem.

I feel like the argument here makes itself. The point of post is that liberals don't actually do anything significant to oppose fascism, or as you put it, only "mildly" opposing fascism.
