I think you explain it rather well. From hearing stories from my friends who are Jewish and pledges christian based groups, they do feel uncomfortable at ritual (that's all I ever get out of them
) but they understand its history.
Maybe I feel strongly about my ritual because of its Jewish values and how many Jewish groups have made the way for being less Jewish and we did the exact opposite, keeping with our values. If there are any AEPi's reading this I hope they get what I mean.
