Seems like Snoop falls into the classic misanthrope category who value the lives of a dog as much as that of your sister, if not moreso. Those types sicken me almost as much as the people who torture dogs, and my mother is one of them. 40 dead kids burned up on a schoolbus from a tossed Molotov, and it's like, "That's sad." But one whimpering dog with a limp. and it's "Death to the perpetrators!" An 8-year-old boy gets shot in the ghetto, it's time to switch the TV channels. An 8-month-old dog gets shot, and it raises $50,000 from sympathizers.
What perhaps bothers me most about these types of people is that the ultimately devalue human life. They seem only motivated by relationships with things that they can be superior to or control. So when something like another human comes into the picture, and thus has the possibility of challenging their authority or dominance (or God forbid, might make them vulnerable), suddenly they aren't of interest to them. They are not worthy of their care or concern.
But if it's something they can dominate or feel superior to, they're all over it as if it were their own family.
