Yes, Tracy, You "knew enough" to avoid dedicating your life to a worthless religion, while the people who were studying with you didn't know enough. Now they hope that their invisible imaginary friend will kill you so that they can be right.
I would suggest that you should not let them get away with their shunning bullshit. Be confrontationally friendly. "Oh, HI! How are you and the kids?" Huh? I couldn't hear you! Has a cat got your tongue, or did your precious organization tell you to shun me because I don't agree with them? Say, how's that whole end-of-the-world thing working out for you anyway? Do you REALLY think the world will end in your lifetime? Didn't you guys say it would end in 1914, and 1925, and 1975, and 1984, and 1994, and before the year 2001? What's today's date, cult-boy? Well, ta-ta, got to be going! See you next time!"
If you do this in public just a few times, the Dubs will run when they see you coming. They'll get their uppity snoots out of the sky.
