The point is that there are a lot of white people (or people in general) who are more sympathetic to dogs than they are to other people -- in particular black people.
depends on the situation i was illustrating how silly that comparison is, when this dude is sick does he go to a dog or a human doctor, and as business as medicine there is still charity in curing, one can even argue charity in most good service. So saying i feel more for dogs than humans i just feel like pissing on the culprit.
