I think this is called "maladaptive behavior" in psychology. You point to bad incidents, find your favorite common factor that makes it easy to categorize the incidents in one bucket, and avoid that entire bucket. "I got pooped on by a duck 3 times, so I'm scared of all creatures who have webbed feet, and they're all to be removed." "I stepped in dog poop 3 times, so I hate all creatures with fur, and they're all to be removed."
