Grabbing your hand? Oh, dear. You make it sound like assault!

I've been to many Masses where the custom is for the congregation to hold hands, and never once have I seen anybody forced against their will to participate.

As it happens, my personal preference is not to hold hands with my neighbor during the Lord's Prayer, but if somebody reaches out to me, I'm not offended. There's so little good will in the world today that I'm not going to reject anybody willing to express it.
