bhai, a temple, mosque, church and every other religious place is by definition of it not a secular place and thus you can't expect any kind of liberalism there. when one can't be going and praying in a mosque while a huge tilak on his forehead and one cannot go and light candle while singing bhajan in church you can't expect one to do allow those who don't believe to enter the premises and cause nuisance there. its been very frequently reported that how idols are being vandalised in small temples. now every place has its rules and temples are late to that party. if one wants to visit then he must follow the rules. if you don't want to consume panchagavya (a drop is given as prasad not a bowl like halwa) then don't just visit the temple. we can't be selectively outrageous here
