Sometimes a Double negative means a positive and these are called litotes, for example:-

  1. If you say you're ex-gay that probably means were gay but now you're involved with the ex-gay movement and think or at least pretend you've stopped being gay.
  2. If you say you're ex-ex-gay that means you were with the ex-gay movement but have stopped trying to suppress you gay nature so you're gay again.
