Well snakes are vemous, not poisonous, which is why it's venomoid, but I know what you mean.
Agree with it? NO - simple as.
People do it to every animal on the planet. Not only do we give animals little respect by often not meeting their needs to suit ours, but start changing physical appearence and attributes so that suits us too.
tailess dogs, barbless stingrays, clawless cats, venomless/fangless snakes, we'd do anything. Eventually most of these practices will become illegal, although herps and amphibians are generally at the bottom of a long to-do list when it comes to animals.
This year saw the law concerning descenting of skunks this year, can't do it anymore. Also there was an amendment to the tail docking of all dogs it's illegal unless it is a working dog of a certain nature, and can only be done by a vet (no breeders).
I'm no tree-hugger but people who feel the need to change their animals should get a robot of their design and a broken nose.
