Most people aren’t going to change their minds over a Lemmy conversation, but a significant number will change their minds over a bunch if conversations.
There’s a Mao quote I can’t find about how party members shouldn’t presume they can change people’s long-held political opinions with just a lecture or two. Deeply held beliefs by definition take a long time to change.
I’m not sure there’s a good definition of this. Your comment makes great points and I read it as respectful to comrades who might disagree, but I’ve seen similar comments called tone policing before. It’s also hard for me to imagine an organization upholding a party line on an issue without some method of policing how its members communicate about that issue.
