I feel like doing that automatically would just encourage instances to defederate if their larger communities didn’t like the cut of another instance’s jib. The culture clash would be harder to tolerate if content were mixed by default like that.
Maybe an easier way for end users to do it themselves? Like making a feed of multiple communities under one topic.
I voted for Sanders in the 2016 primary. In hindsight, he would have been obliterated, McGovern-style. Clinton and Biden treated him with kid gloves, but in a general election all of his questionable past – his unemployment, his wife’s involvement with that college financing thing, his honeymoon in the USSR, the rape essay – would have come out and been hammered relentlessly by Republicans (and a good chunk of Democrats).
