JW's are quite literally parasites. They are happy to to use up the blood that others have donated, but they will not contribute any themselves.
They are taking advantage of the good grace of their fellow humans. This is a completely morally bankrupt position, an absolutely disgusting double standard. The jw's wrap themselves up in a cocoon of self-righteousness and an insufferable attitude of superiority when in actual fact they are nothing more than slimy leeches sucking the life blood from society.
