You certainly don't want yucky undesirables to have shelter when homeless, to be fed when hungry, to be clothed when naked? Just because they happen to be the same species as you? Just because their blood is the same color as yours? Just because that's the moral teaching of every dominant religious system? No, some people should be homeless, and suffer, and be made to bear humiliation. It is self evident that the suffering of the marginalized is a social good which the people must not be deprived of.

You see, the only reason people are homless or otherwise down on their luck is because we make it so darned comfortable for them. If we can just make it sufficiently unpleasant, then they'll stop doing it.
