The reason a JW can not even say 'hi' to me (and most you here) is based on 2 John 6-11
6 And this is what love means, that we go on walking according to his commandments. This is the commandment, just as YOU people have heard from [the] beginning, that YOU should go on walking in it. 7 For many deceivers have gone forth into the world, persons not confessing Jesus Christ as coming in the flesh. This is the deceiver and the antichrist. 8 Look out for yourselves, that YOU do not lose the things we have worked to produce, but that YOU may obtain a full reward. 9 Everyone that pushes ahead and does not remain in the teaching of the Christ does not have God. He that does remain in this teaching is the one that has both the Father and the Son. 10 If anyone comes to YOU and does not bring this teaching, never receive him into YOUR homes or say a greeting to him. 11 For he that says a greeting to him is a sharer in his wicked works.
This type of treatment is only ever described at this one scripture and is being applied to the ANTICHRIST.
I wonder what my overly active JW mother thinks about spawning me; the Antichrist? It makes me feel like I have just appeared out of some blood sucking vampire movie.
