It's a rather sad reflection on ignorance and an almost spiteful attitude from someone in 'public education', isn't it ?
Even Captain Beaky and his band had the snake as their enemy though...."hissing Sid has eaten Toad!!".
My bother bought my kids a six foot rubber snake. We still call it (for it's draped up the rafters in the loft to this day) Hissing Sid

It scared the living daylights out of my moggies

Great fun and amusement watching a cat watch a rubber snake and sort of go all manically puffed up, back arched and hissing like an overboiled kettle
Talking of bothers, that same one was clambering over the rocks up at the David Marshall Lodge on one of our family outings.....fifty years ago, at least, and he disturbed an adder. Little blighter was fascinated while my Dad told him to leave it alone and come down !
Cue a plummy voiced felllow making noises about having to deal with, 'the beast'. My Dad told him just to let it be, it would only bother folks if they bothered it.
So, we kind of grew up with the attitude to just leave snakes in peace.
Didn't stop my bother going looking for them though
