if they try to impose their religion on you in the song circle, say we have many religious faiths and lack thereof here, so we try not to get into religious discussion in the song circle. In fact, the more talk that goes on in song circles, the worse the flow of music is, it seems to me anyway. Now, at the refreshment table or privately, just say you have your own religion and change the subject. Maybe tell them some of the old traditional numbers you like to hear.
