"Churches do treat non-christians differently. Non christians cannot receive communion. But they can attend services. But this also about taking a common sense approach to things. " How, pray, is this the common-sense approach? This is merely the approach you prefer. Using words like common-sense is merely a way of privileging your opinion above others.
"The head tantri is hiding behind the age old i-didnt-set-the-rules-all-i-can-do-is-strictly-follow-it excuse that fundamentalists use all over the world." More nonsense. All this palaver is merely your opinion. In fact, I found the tantri's explanation more elegant and his understanding of right and wrong far more clear-cut than yours.
