Me: "Yes" 
Lmao I wouldn't even call me an angry person. I'd call me an empathetic person that is responding naturally to a shitty system.
Being submissive isn't a virtue. You just dislike justified defiance because it makes it harder for you to pretend everything is okay. It reminds you of your cowardice.
Yes. There is a reason we still have the phrase "righteous anger" percolating in the English language. Seeing injustice elicits shock, horror, and heartbreak. It is completely 'rational' that those emotions transition into incandescent rage. If I saw a dude kick a puppy my first emotional reaction is gonna be "Holy fuck did I just see that dude kick a puppy?" My next emotional reaction is "I am going to kick that dude's ass." Completely normal chain of events.
Yep, capitalism rewires you to deflect your anger against the things capitalism wants to (or is indifferent to) have hated. Communist theory enables us to both see, and crucially, articulate the real causes of injustice that should be targeted. It is emotionally taxing, however. It can give us short fuses and leave us coming across as "hot headed" or "angry all the time." Well no shit! Capitalism is systemic, it's totalizing, and it means we see shit that should be bothering us all the time. Couple that with the fact that lots of people are content to ignore this tornado of shit that whirls around all of us and it can be very isolating. Sorry I kinda meandered a bit there but it's one of the things I think about a lot.
Thanks comrade. This place is truly the best little corner of the internet.
