I understand this is a social game but it's becoming tiring that most of the posts on this sub are advice on social dynamics rather than commander itself
Is communicating that hard? Setting boundaries? I want to read content on the actual game itself not the interpersonal drama you're unable to navigate through. Oh, Player A is trying to break the rules with a Rule 0 discussion and some people are okay with it but I'm not. Cool, then don't play with them or communicate why you're uncomfortable with that level of compromise. Oh, Player B acts aggressive and whines when we stop their wincons. Cool, then don't play with them or tell them no one is entitled to winning without others trying to stop them. Oh, Player C has messy proxies and plays decks that are way too strong and also likes to underplay how strong their decks are so they can pubstomp. Cool, then don't play with them or actually talk to them about your perspective and why they aren't good at the game if they have to resort to petty tricks to secure a win.
If the root of your post is how you engage with another person in a social dynamic, then there are better resources for self-confidence and communication than the EDH subreddit.
