OMG! I can't believe it! I have had the EXACT same feelings for many years. I was embarassed to invite anybody of reasonable intelligence to the Memorial because of the things you mentioned.
number one thing on people's minds at that moment is "Oh dear gawd, please don't let me or my child be the one to spill anything!" The number two thing on people's mind is "I wonder what bat-shit crazy person is here tonight that is going to partake?
Those actually were the first and second things on my mind.
They insist on having each and every human being in the hall touch and hold the plate or wine glass.
I always thought that was so strange & weird. When I gave the Memorial talk and they offered me the emblems, I just shook my head "no" in a firm and dignified manner and didn't lean toward or reach toward the emblems in any way. I didn't even look at them. The last year I went, I was standing in the back. When the servers offered me the emblems, I had my arms folded and I just shook my head indicating "no".
As if the momentary touching and holding of the plate or wine glass is somehow a "Holy" experience.
Yeah, like you gotta have hands on the cup or plate or you're gonna incur the wrath of the Sovereign or you won't get credit for being there.
JWs can't/don't think for themselves; they just follow the crowd. They think "well, since everybody else is touching the cup & dish, I guess I'm supposed to."
It's ironic that JWs think they have discernment; they're the blind ones. I think it's people like us who can recoginize what you mentioned in the OP who are really the ones who have discernment and can "see" and recognize truth.
