I guess it is just the kind of snakes that you are used to. I have lived my whole life around nothing but copperheads, coral snakes, water moccasins and rattle snakes. So all snakes are evil to me.
I grew up with 3 of the 4.
Didn’t play with them but wasn’t bothered by them.
Just kept an eye out for them around my animals.
Ours generally stay up on the mountain and the Cottons were only down in VA/NC where we vacationed.
They just swam by you and went on their way.
