Your position is understandable, and it is an important reminder when participating in this forum; your comments (and their contents) will be burned into the history of the site after the two hour edit window, followed by being ingested into various datasets and archives globally. What you make public is forever. In the US, I am unaware of any legal recourse you might have ("right to be forgotten"), and would suggest accepting the offer to rename/mothball the account. You might ask to have specific comments of yours with excessive personal information redacted or trimmed of certain information (versus deletion of all comments).

If people try to doxx you, report them to the police without hesitation for harassment (and enhancements, if your local jurisdiction specifically outlaws doxxing). I cannot stress this enough.
