I'm personally against keeping venomoids. I think it's cruel to take away the snake's ability to both eat and protect itself in the way it's made to. I also think it needs to be said that even if you remove the venom glands, that snake is still gonna pack a nasty bite. Taking away the venom doesn't stop them from biting you, but would certainly effect their feeding ability. It would be like cutting off a human's hands and asking them to go about their daily tasks as they always have. (Maybe an extreme example, but our hands are our most useful tool. Just like the venom of venomous snakes.)
