For your first point they smugly post the “you can participate in a society while wanting to better it” comic as if it’s the end-all gotcha.
I can understand say, having a smart phone and using it to spread an anti-capitalist message. I can get the concept of using what you have access to as a necessary evil. But somebody who is “anti-capitalist” with a collection of Funko Pops, all the Marvel Movies rented on Amazon Prime, and a diet of fast food is just a loud mouth hypocrite.
Sometimes I scroll the histories of CTH posters. I see tons of posts in videogame, “battle station”, movie, and other highly consumerist subreddits. I’ve yet to come across a CTH poster who is also active in gardening, DIY, car repair, or any other sub designed to help them extricate themselves from the society they hate so much.
