This Sunday Steve Maxner, a Viet Nam veteran and environmental activist, will speak at the Unitarian Universalist Church on the topic, About Protest. Mr. Maxner recently paddled a yellow kayak near the award ceremony at the Monster Shark Tournament in Oak Bluffs. His small boat carried the words, “Killing Sharks for Fun and Prizes is a Crime against Nature — Shame on Us.” During the talk on Sunday, Mr. Maxner will compare the feelings he experienced protesting the Shark Tournament with those he experienced as a protester after he returned from Viet Nam. He will present two songs he has written, one about the Viet Nam experience, the other about killing sharks, and accompany himself on the guitar.
