At least tinrobot is honest when s/he says "if I thought whales were the biggest threat to my loved ones, I'd kill the whales."

Dealing with them here in the West, I notice one group thinks the feral horses are the most important - to the demise of habitat of other species in the area. Others favor a mouse to the exclusion of reptiles.
