A user very active on this site in the comments of this answer (https://politics.stackexchange.com/a/82516/28966) was, in my opinion, using and justifying ethnic cleansing euphemisms, and I called it out. The discussion got a bit out of hand, and I anticipated it being moved to the chat, which I was absolutely fine with.
However, it seems a moderator simply...deleted the entire conversation, without any notification in my inbox of it being moved, or a moderator comment explaining that it had been moved. This seems quite strange to me. The discussion was very much on topic and related to both the question and the answer. However, as it was getting extended, by all means it should have been moved to the chat.
What is the justification for wiping comments like this? Is this normal in this community?
If it is necessary, I can describe the conversation, but I doubt that is necessary and I'd rather avoid it as it was very distasteful in my view.
