Just because bad behavior is limited to a few doesn't mean there's no reason to care about bad behavior. Keeping most people playing by the rules generally require that we care how each other act, that goes for science too.
I don't think this is any sort of disaster, that's why I only made a very short response to it in my response to the OP and focused on their findings instead, but I do think people should care when scientists start being divisive by bringing their biases into their field.
