Well what you want comes with consequences. And the consequences are people teasing each other and poking at each other.

Large groups of people almost never universally get along. You can federate with this half, but you'll have to be okay seeing opinions and talking to people who you just don't always agree with.

I think most people can't handle having someone, or entire groups of people disagreeing or disliking them. All groups "haze" to a certain extent. Even on your "side" of the fediverse, I am mostly not welcome just be default, or I have to cater what I say to not offended anyone.

Plus stepping on eggshells all the time doesn't lead to good or valuable conversation.

The other problem is in itself the mind set of "why can't we all get along". You just can't. You can't possibly find common ground with everyone. When you factor in the sheer diversity of experience it's super ignorant to assume you can just be yourself and everyone will like you. Sometimes when you disagree you just have to not respond or you'll get into an argument. I think they key is more emotional intelligence and not assuming because someone has a specific belief they are "all" bad. You don't have to agree with someone on EVERYTHING - you can still post fun memes and give each other shit in good fun while keeping your own values and allowing them to have theirs.
