First off this guy doesn't even have a PhD in psychology to even use anything he used as a reference or even an expericene with reptile keepers either. Who ever this guy is, is a VERY uncrediable source.
And here is the thing dogs killing people are about 100x's more common than a snake killing a person. Seeing there has only been 1-2 cases of pythons/boas killing a human.
Im sorry but there is more of an issue with wild boars and cas/dogs out in the world than their are snakes and hate to break it to all the I hate snake ppl, but they cause more terror and problems than a Burm/boa or ball.
If I ever met this dude I would let him pick between a room with a 20 foot burm who's a pet and a fighting dog of some sort. I bet he's dumb enough to pick the fighting dog and then he would be torn to shreds by something "that is less dangerous" than a snake.
