The other way to look at it is that in some areas, rattlesnakes are not nuisances due to scarcity, and also due to scarcity they are protected.
I am not sure how that translates to hatred or anti-hunter sentiment - unless you are saying that hunters don't care about elimination of a species. If that is what you are suggesting, then you should look first at yourself, if hunting gets banned.
Do you feel that Rattlesnake hunting is legitimate hunting?
