People of all the Indian Faiths ( Jain, Buddhist & Sikh) should be allowed into the temple & treated on par with Hindus if they wish to have darshan - at the same time we should respect their desire to preserve their religious identity (as Sikh, Jain etc)
I have no comments on non-admission of people of other faiths but I feel personally hurt that singer Yesudas should have been denied entry.
