Others might have a better answer, so I'll allow them to make suggestions. My commentary stems from holding similar views on Communism/Socialism, until I decided to actually dive into the theory. I've listened to the communist manifesto, and working on listening to Capital currently. I'd like to eventually read Black Shirts and Reds by Parenti. Having a good foundational understanding will help you evaluate our current place and time through the lense of these political ideologies and help avoid simply barking shibboleths at the moon.

Idk if you're asking about specifically anarchist reading here, if not:

• Principles of Communism by Engels is a good essay-length read ( https://www.marxists.org/archive/marx/works/1847/11/prin-com.htm ).

• State and Revolution by Lenin is a great first short book length read ( https://www.marxists.org/archive/lenin/works/1917/staterev/ ).

• On Authority is Engel's argument essay against Anarchism and the term "Authoritarian" . That may or may not be up your alley, but you'll see a lot of that reflected in what we say here ( https://www.marxists.org/archive/marx/works/1872/10/authority.htm ).

• And just because Mao is rad, "Oppose Book Worship" includes the banger "no investigation, no right to speak" and I like that. ( https://www.marxists.org/reference/archive/mao/selected-works/volume-6/mswv6_11.htm#fn5 ).

If you're looking for Anarchist theory you could try an Anarchist instance. I think they like Bookchin or something like that.
