The Federation Safety Enhancement Project calls for use of TBS. The TBS privileges mastodon dot art's blocklist. The mastodon dot art blocklist blocks a lot of bad actors, and a lot of good actors.
In effect, widespread adopt of the FSEP proposal would mean cutting anarchists, among others, out of the Fediverse.
And any criticism of the FSEP or TBS is immediately described as a racist attack on one person, regardless of the criticism.
