At least you are still going!
My brother is the absolute worst on not having gotten into the ‘new’ Mass. Don’t think he’s ever missed a Sunday or Holy Day Mass in his life BUT ... He won’t do the peace thingy. Just won’t do it. Don’t even MENTION the women who help distribute the host. Always gets into ‘debates’ with the priests. Just a joy to have in the parish ;)
I feel as your brother does, although I do not argue with my priest. I will not do the handshake, although I grit my teeth and feebly wave at people. Also, I avoid receiving my Savior at the hands of anyone but a priest, and I especially resent the female extraordinary ministers.
