I don't use Facebook, which is maybe why I don't care how they manage their service and also why it seems clear to me that there are other social media platforms, other web sites, I could make my own web site, hell I could send letters in the mail. Suffice to say a single message being deleted on Facebook is not censorship of the individual that had this issue.
