I would first of all, like to thank George Iype, the author, for bringing this issue to light.
I myself am a hindu and a believer of Lord Krishna. There have been a couple of occasions when I have been able to go to Guruvayoor. I remember the first time I went there and saw the board outside which restricted non-hindus from entering the temple, I really felt shocked.
Can someone tell me, what makes the Guruvayoor temple alone, so privileged! Sabarimala sees a lot of non hindus every year.And a lot of hindus who go there visit Vavar Swamy (He was the Muslim lieutenant of Lord Aiyappa) first and then proceed to visit Lord Aiyappa (Note: This is a tradition that has been prevalent for long). My point here is that Hinduism is not a religion that objects to others believing or following it. Another example here could be ISKON (International Society for Krishna Consciousness).
So, finally, what are we talking about? A bunch of self proclaimed architects of the religion called the "Guruvayoor Devaswom Board" who sit there and decide what is right and what is not!!! Gimme a break!
