The main subject was the entry of non-hindus in temple. But subject derailed in a direction of supremacy of brahmins. What is the relation. All scripts and upanishads are not written by any brahmin. They are written by Rishis, nobody knows who they are. Many brahmins appointed them as their aboriginal forefather just to claim the ownership and rights on scripts. Veda Vyasa who is the creator of 4 Vedas was son of a fisher woman. Right from that time, knowledge was not the property of any caste.
After several years of experiments, Adi Sankaracharya found Advaita which is the core of indian philosophy. Today brahmins are in high jobs not because of any intellectaul capability, but they had access to schools run by britishers and other did not have. Means, Brahmins had over 100 years of reservation in schools and employment.
In this century at least, can't people think beyond caste, creed and sect and cult and all. If you believe in god, why can't people see him in everything in this world. How come muslim is different from a hindu, in what way ? How can one say Jesus Christ is worse God than Krishan. What is the comparison ? Hinduism see only one god which is Parabrahmam, all other things are its manifestations including every linving and non-living things in this world and gods like krishan, siva, jesus, allah all.
Open the doors of temple for anyone who wish to find God in there.
