you should def not go! If I may be so bold as to suggest the next time they call, ask one of them to dinner with his family. isnt that what a christian would do to get to know and encourage a fellow christian? after all, where two or more are gathered together..... Let him try to disrespect you and your family in your house. In front of his wife and kids. In front of your spouse and kids. If he does disrespect you then show his family the door. Let it be another example to your family of the insane behavior of the jdubs. It will be an excellent example to his wife and kids, even though it might not sink in at that time.
Of course they will not accept the invite. They dont have the balls. But avoiding them in my humble opinion is like seeing them out in public and trying to hide from them. If they see you first and you dont make contact with them they will be able to go back to the hall and say "oh i saw brother/sister inactive today, they seem so sad i really hope they turn around and come back to jah. dont give them that!! walk up to them, say hello, make them uncomfortable for their poor decision to shun you. they are the ones who are being dicks, dont ever let them pity you. The liberation in life you get when you finally tell yourself you will no longer live under the thumb of religious hacks is incredible. god knows its not easy but nothing worth having is.
