I just assume that the far-right nutjobs are a small minority and as long as this is true, I prefer them getting drowned in one huge community over many small walled communities which only federate with a small group of similar-minded instances. Thats all. Basically the same as we had on Reddit with one large community but many different /r/ Its totally fine if you have another preference

When Mastodon was tiny but already stuck in the left-right battle, it was just a bit extreme imho. Some Mastodons allowed everyone in, some hat a banlist of far-right instances, some only federated with explicitly pro-LGBTQ instances (but always incompletely, since the community is always rapidly changing). This makes it difficult for new users to choose the right server. If Lemmy/Mastodon/whatever has 100 mil users or more these things stop to matter, of course. But before I would rather have one large platform growing

GTIO is an interesting concept, though, and solves the problems I assume maybe. Thanks for the link, I didn't know about it, will check it out
