I would say no, I am not going to socialize with people who treat me like a second-class citizen--let me know by ##/##/2016 if you change your mind, otherwise I will make other plans.
By "people", I am referring to the non-jw relatives who are insisting upon this. Say if you want to participate in a cult's shunning ritual, you will have to do it w/o me.
My saying is always, "You be normal and let them be the weirdos."
Oh, whoops. I see you already attended & refused to leave. Good for you!
