People block or mute because they can I suppose. I'm guilty of blocking people that spout off Qanon conspiracy nonsense or people that make racist comments. One of my favorite writers here, blocked his readers ability to comment on his articles completely. I'm sure he had his own reasons for doing it, but it made me sad because I enjoyed interacting with him. Who knows? There are plenty of readers and writers here that are very courteous and I look forward to seeing more from you.
