Fun fact: there was a famine in the USSR immediately following WWII. But after that, “bread lines” weren’t really a thing in the USSR until the late 80s, when Gorbachev threw a bunch of market reform monkey wrenches into the works which directly caused the “bread lines”.
I had a roommate who was homeless for 20 years prior who made a Soviet bread line comment. I pointed out you gotta wait in line to buy bread anywhere, at least this was free, that totally changed his tune. He didn't know it was free bread. This was a dude who knew to get up early on Sundays cause churches did free meals those days and he'd go church to church, pack up those meals and store em in the fridge and that was his meals for the week. Once he realized it was a less painting the ass version of what he was doing and also guaranteed on not reliant on churches that he wasn't too into he changed his attitude immediately. It's amazing how anti communist propaganda makes something pretty normal into some sign of dystopia.
The easiest anti capitalist own is to remind d people to compare socialist states to other states that existed contemporarily or historically instead of comparing them to the absolute extent of ideals that you don't even believe in. If you can't do thst for a different ideology than you must do the same for your own.
