In the 'most inconvenient world' it constitutes a mugging.

If your claim was 'I can imagine something like this which would be a Pascal's Mugging' then you should have said that. What you actually said was that it was one, and you don't get to use 'least convenient possible world' when you're making statements about the actual world. You made a false claim, encouraged others to make similar claims and contributed to the loss of a useful term from LW vocabulary.

I get to use 'least convenient possible world' when I said that there are:

often messages posted at least superficially similar to the following

and gave an example of one claim that could be made.

I think that conversation would be best continued in messages.
