Socialism

I was a far-right lunatic until about 2009, when I started turning left. I have read many (center-)leftist articles from Jacobin, Common Dreams, The Guardian, and, from Brazil, Carta Capital and IHU (Catholic liberation theology).

Lemmy (despite my suboptimal instance) and communist friends got me interested in actual Marxism, but I have not yet really studied it. So please recommend:

• The best Marxist Lemmy instance for my background.
• Marxist books or videos in approximate reading/watching order. For the next many months (I suspect six months) I will have very little time, though.

Bonus:

• reasonable tolerance of Catholic faith and individual morality
• contextualized on Brazil, Cuba, broader Latin America or China

Background: Brazilian Catholic male autistic ADHD IT analyst with an electronic engineering degree and MsC in computer science. I have a son with my wife. I highly value privacy and software freedom. I read English well, but Spanish quite poorly. Native Portuguese speaker.

EDIT: I got a lemmygrad account. I am still processing the other recommendations.
