You’ve ACTUALLY missed their point with the comic (who the fuck is calling a comic a meme?) tho. The fact is that capitalist society, especially in the US, has pushed even the socialist calling for change to live in the system, even though they’d rather not. The consumption of coal and oil are forced choices because someone isn’t just going to fuckin go without shelter or the ability to get to work. Your “SoCiaLisTs dO It tOo tHo!!#'$^=!” statement is crap because consumption of those products isn’t a choice anymore.
Even socialist states that fail on the climate front are because they’re competing on a global scale with capitalist cultures that just completely ignored that for a century.
