I feel ya man, I did a presentation of why people are afraid of snakes for my public speaking class. Just refer to the biblical stories, and how If people are raised to believe that snakes are dangerous, they will believe it no matter what. "SNAKE" is a very broad generalization. Where Im from, when people when people hear the word "snake", they think of venomous rattlesnake, just be sure to inform your viewers about BP's and how harmless they are
Think about this, if you know NOTHING bout snakes in general, then you go see the movie "Anaconda" where the snake Is 100 ft long and can FLY, you're going to be afraid of snakes. Lol just present about how awesome BPs make as pets.and how they aren't like other snakes,
