Fosstodon, the popular instance that hosts many FOSS open source software developer accounts, might get blocked by multiple Mastodon instances because of an alleged alt-right moderator on their instance. This sucks and I'm unsure what to think about this

Drill down and find that the issues are the ones that typically divide the right and left in the US. These opinions make the moderator an outlier to one political camp, but normal to the other, in a country divided roughly down the middle. So enforcing a block due to this person's opinions will be precedent for blocking any moderator who aligns with the ideology of about half the country. It's similar in effect to declaring "no Republican moderators".

I'd guess that a plurality of Mastodon users are OK with that. I fully support the right of Fosstodon or Mastodon to do so on freedom of association grounds. But I prefer more inclusive communities like this one.
