^If someone wants to argue with you, you CAN use it as an
  opportunity to get stronger. A battle of wits has invisible
  swords and armor but they're there just the same, and when they
  say "you're missing the point" you can laugh - because that
  means they failed to stab you.

  But, also: if someone wants to argue with you and you just don't
  feel like it, you can be the first to walk away.

  They can call you any names they like - and they will; but you
  walk away the better person. You didn't go down to where they
  are, in the mud of battle and you walk away clean.^
