why sign stuff, i can help clean local park in hammer and sickle hoodie well enough, get "you alright for a commie" and not meet those people for a year, i think its a worthwhile pursuit (despite it basically being state offloading its duties on free labor). there are lots of hobbies where you can indirectly imply your politics (without proselytizing until you are liked enough) while being friendly and helpful. getting third spaces is hard without beaucoup bux, getting in third spaces is usually free.
