Do Jehovah's Witnesses "love" their enemies, Like the Pharisees did?

I asked a JW if it is showing Christian "love" when they are told to "hate" a person for leaving their religion. The answer was "yes, we are told we cannot speak with , say a greeting to, or in any way have anything to do with them beyond directing them to their needs in a business setting." I must ask, "How" is this a show of "Christian love"? If the departed or "ex-member" is now considered as a "tax-collector", or "man of the nations"?, didn't Jesus actually speak to, and take flack from the pharisees for doing so? Are the Jehovah's Witnesses acting like Christ, or like the Pharisees???
