"My goto guy for double checking my logic reminds me that I am
  relying on relevance logic without having explained relevance
  logic to people who are relying on classical logic. So he
  indicates I am in the wrong for assuming everyone would be on
  the same page. Assumptions are wrong in logic."
  was marvelous (and the apology following is a pragmatic matter;
  social lubricants are useful tools)

  So:

  Relevance Logic is Logic.
  Classical Logic is Logic.
  Relevance Logic is Classical Logic.
