seriously. it's not that big a deal. if people in gaza are still standing up to their oppressors every day then you likely have zero excuse for not doing more IRL shit (political reading and writing at home are good, but don't mean anything if you're not applying that theory as practice and then assessing the results and adjusting your practice accordingly).
I would not be so sure. From what I have read party members in the Indochinese/Vietnamese Communist Party explicitly described themselves as having a sibling-like relationship with each other and sleeping around in the party would cause scandal. At least one man was executed by other party members when a woman comrade reported him, though there might have been some SA behavior going on in that case. I'm pretty sure that the CPC was similar in that regard too. I also believe Trotsky had somewhat of a "reputation" within the Bolsheviks for that sort of thing, which seems to indicate it wasn't that common there either (or that could have just been made up one of his many haters).
Not saying it never happened in history but ultimately people should be there to work and it's the same problems with dating at work, and those problems multiply when you're trying to run the party as an honest to marx people's liberation army. It did seem more acceptable later when those parties transformed into government bureaucracy though.
I'm pretty sure Mao met at least 2 of his wives through the Party. Reading Red Star Over China makes it seem like that wasn't unusual for early CPC leadership either.
Didn't Rosa Luxemburg meet her partners through organizing?
