What's the difference? We're all animals. Look what the pure-bred European royal stock did during WW I. They nearly destroyed themselves and the world.Are you talking about dogs or humans?Nope. Inbreeds are what happens when close relatives boink. A purebred is from sufficiently diverse stock which keep the breed pure. A mutt is a mutt.Better "mongrel" vigor than "pure-bred", just another word for inbred.Obama is a hood mongrel compared to Reagan, a pure-bred champion.![]()
