Blocking someone should remove their replies from your posts, this is the type of safety features we need in the Fediverse!
If you have a fediverse account, you can quote this note from your own instance. Search https://mastodon.social/users/dansup/statuses/116094075872982176 on your instance and quote it. (Note that quoting is not supported in Mastodon.)

When you share a new blog post to your blog, you are able to remove comments.
The same should be possible here, and no, I don't mean delete the local/remote comment/reply, I mean detach it from the conversation thread.
I've been called a fascist for wanting this, but it's not that different than how a blog works lol

Totally agree! This is exactly what #GoToSocial's interaction policies already handle with Accept/Reject for replies. The missing piece is retroactive rejection. When a reply was auto-accepted by the policy and you later block the author, the server should send a Reject on the original Create activity to unlink it. Extending their framework would be the cleanest path.
