I post good faith comments and expect a good faith response, you know a conversation.
But someone who posts an conservative article in a conservative community is under no obligation to have to discuss it. Many like it, post it, and move on.
If it’s an echo bunker of misinformation and lies that doesn’t welcome opposing opinions then just be honest about it
And from what I see on Lemmy, that perfectly describes Lemmy as a whole.
Also, as far as I know, there is no way to make a community private. I WISH there was though. Or if there is, please tell me how to do it.
