As it turns out, art (or theater) can change the world. It just takes people to start the conversations. Gwydion Suliebhan’s world premiere play “The Butcher,” running through March 22 at Gulfshore Playhouse, is proof of that. The play, inspired by real-life events, looks at people and how they exist in today’s secluded, self-selecting and often self-delusional world.
