Much of it seems to be a matter of what we think Lemmy and the communities are for.
In my mind, c/News and c/Politics should be group spaces where people of all stripes can express view points in well-reasoned, civil, ways. I have no problem with little corners of the federation that cater to the hurt and angry, my issue is when it spills out into the more public spaces. I will readily acknowledge some of that opinion comes from a stance that does not seem all that popular on Lemmy.
When I first heard about the fediverse, I was excited that the echo chambers would be broken open. I thought everyone could have their radical little corners, but that there would be open communities that we could all meet in and discuss issues in a reasonable way.
When I joined an instance with a “democratic” experiment going on, I quickly realized that my view that it was awesome to federate with everyone was a relative minority; many people there thought it was more awesome to be able to defederate from those whose opinions they never wanted to see. Fortunately, their community found something of a middle ground, but it was still quite the disappointment to me.
