In other words, "Don't copy me - what I'm doing is not really right."

I can't see anything ludicrous about that. There are all kinds of reasons why anybody might do things that they would prefer other people didn't do, and which they can't really justify.

What is ludicrous is when people pretend that whatever they happen to decide to do to suit themselves must be right. And that's what most people in public life seem to persuade themselves is the case.

The truth is, people aren't perfect and shouldn't pretend they are. It doesn't fool anybody anyway.
