I know this is one of the very unfortunate incedent...after reading this interview what i can understand is no one is sure what Adi Shankaran actually might have conveyed as there is no written rules available...Tantris have liberty to mend these rules...So I believe they have done is and still trying to enforce it...
This is not an issue with Hindus alone...I have seen this even in muslims...some of the very pious muslim people dont eat non-veg from non-muslim restaurants...understandably because of hallal thing...but i have seen people not driking water from a non-muslim people...
yesterday somebody was saying some one wasnt allowed into the chruch in russia cuz she wasnt a chirstian...
so this crap exists in every religion...and you dont need liberlisation to thing this is unfair...all you need is a lil commom sense...
