There is liberal anti fascism and autonomous anti fascism. Liberal (e.g. using lawsuits) anti fascism is good, but never enough alone.

You have to deny fascist speech, because fascist speech equals fascist recruitment. You have to deny them platforms. The early age of the internet made that impossible, and many nerds like me had no clue about this. Freedom of speech warriors against stupid governments etc. Much of that was correct, but what got forgotten is that you need active moderation and laws to limit hate speech from proliferating. And neoliberal governments never pass those. Like fascism, neoliberalism believes in inequality.

This current wave of fascism is a long time in the making with the ultra conservative and christian talking points and rural talk radio. When talk radio started ranting against abortion, THAT was the time you should have started autonomous action to stop their continued broadcasting abilities.

I learned the political theory for anti fascism way too late. This is a good book review on this.
