There is something that all of you need to remember when people question the intelligence of keeping snakes.
YOU don't have to be the Reptile Ambassador to the world. It is OK to say NOTHING. It is OK to tell them that while they are woefully ignorant of the facts, you hold no personal animosity for their willful ignorance. It is OK for you to simply shake your head and walk away.
Sometimes it's the best thing you can do, be silent and leave, especially if you're a hothead. After all, any one of us is seen to represent ALL of us and frankly, there are a LOT of folks who have snakes that I wish either didn't, or simply keep the fact that they did, to themselves.
It's OK to just let it go when you know what the outcome will be, especially when you know the person making foolish statements has NO desire to know the truth.
