Authoritarianism

This is an irrelevant observation since any government that wants to survive is going to engage in methods that others will inevitably regard as ‘authoritarian’. You may as well say that fascism and communism are the same because fascists and communists both wear clothes. Who cares?

Ideology revolves around common enemies - In fascism this comes in the form certain [sic] ethnicities or nationalities

I like how the author conveniently forgot to mention fascism’s war on socialists. Also, one could just as easily argue that anticommunist ideology — in general, not only fascism — revolves around common enemies as well.

Bitterly oppose materialism - Fascism opposes materialism because it is deemed to lack acknowledgement of the role of the spirit, while Marxism opposes materialism because it is deem [sic] to be a key engine in class warfare.

I think that what the author did here was first use ‘materialism’ in the scientific sense (the principle that everything that exists is material), then used the word in the sense of avarice. This certainly wouldn’t be the first time that an anticommunist forcibly made a clunky false equivalence, and it won’t be the last.

Explicit support of political violence

Anticommunists: famous for never endorsing political violence!

Marxism calls for […] killing the entirety of the bourgeoisie

When you look at the more pragmatic ideologies around, you’ll notice that they don’t have enemies that define the ideology. Take for example, modern day social democracy. Who are it’s enemies? It doesn’t really have any. The ideology is more focused on specific values and approaches to issues rather than trying to define an enemy group as the root cause of everything. The same goes for liberalism.

islam as an ideology revolves around fighting the nonbelievers because they are ignorant sinners

I think that I’ve had enough.
