I’m reading through Kropotkin's The Conquest of Bread, and I can’t help but feel like he predicted leftist Twitter:
Possibilists , Collectivists , Radicals , Jacobins , Blanquists , will be thrust together , and waste time in wordy warfare . Honest men will be huddled together with the ambitious ones , whose only dream is power and who spurn the crowd whence they are sprung . All coming together with diametrically opposed views , all — forced to enter into ephemeral alliances , in order to create majorities that can but last a day . Wrangling , calling each other reactionaries , authoritarians , and rascals , incapable of coming to an understanding on any serious measure , dragged into discussions about trifles , producing nothing better than bombastic proclamations ; all giving themselves an awful importance while the real strength of the movement is in the streets .
(Kropotkin, Petr Alekseevich, kniaz. The Conquest of Bread (p. 27). Public Domain Books. Kindle Edition.)
Political infighting (especially on social media) is ultimately pointless. Get out in the streets and actually work to improve the world. Even one tiny direct action is worth hours of bickering in comments.
