similarly the important question in this matter is - did the founders of temples have any ULTERIOR MOTIVE in not allowing non brahmins as priest in orthodox temples? my answer is a BIG NO!!! pls. consider the following-
1. even brahmin gods of rival sects cannot enter sanctumsanctorum of orthodox temples!!
2. even brahmin priests of rival sects cannot enter sanctum sanctorum!!
3. even brahmins born outside priestly families of same sect cannot become priests or enter santum sanctorum of orthodox temples!!
the above facts clearly proves that our forefathers & ancestors did not have any ulterior motive in disallowing non brahmins as priests in orthodox temples. had they allowed all brahmins & disallowed all non brahmins then the charges of 'discrimination' & 'untouchability' would have had some meaning. but the fact that they have imposed restrictions even on brahmin gods, brahmin devotees and brahmin priests also clearly proves that there is no proof of any ulterior motive. so the charge of 'discrimination' & 'untouchability' is absurd and i am dismissing this charge with the contempt they deserve!!
This is a classic example of the clever ploy of varnashrama.
In Islam they clearly divided the world into two.Muslims and kaffirs.They called muslims as superior to kaffirs and started oppressing them.In christianity they divided the world as believers and infidels and started oppressing non-believers.later on this helped the oppressed to oppose these religions as a solitary group.There were civil wars and revolts against this oppression.
However such a revolt never happened in hinduism till 1950. Till ambedhkar, periyar , kamarajar, vaidhyanatha aiyyar and gandhi appeared in the scene, there was no revolt of any sort that happened in hinduism. The reason for this is the clever and ingenious ploy of varna system.In varna system, they divided the society into 4 major categories.Among these catgories they further created sub divisions.
For example according to varnashrama, brahmin is superior to ksathriya,vaisya and sandala. ksathriya is inferior to brahmana and superior to vaisya and sandala.vaisyas are inferior to brahmanas and ksathriyas,but are superior to sandalas.Thus in this system ksathriya and vaisya was made to believe that he is benefiting and honored because he is told as superior to sandalas.
dalits were made to stand outside temples.The next two varnas were made to stand outside the sanctorium.Among vaisyas and ksathriyas, ksathriyas will be given preferential treatment by way of "parivattam" "muthal mariyathai" "special archanai" etc.But still they wont be allowed entry into sanctorium.
The other two varnas thought this as a honor.They were happy with the fact that they get a better treatment than dalits.This made them forget that they get a lower treatment than the upper varna.
even among dalits, there were varna divisions.A sakkili was lower than all, he will be humiliated by all 3 varnas.But this wont stop him from humiliating thottis.He will consider himself as higher than thottis and lower than vaisyas.He will insult thotti and get insulted by other 3 varnas.
Similiarly even among brahmins there were caste hierarchies.even though brahmins are superior to other 3 varnas,among brahmins savundi brahmins were considered as lower to all.Gurukkal was considered to be more superior in hierarchy than savundi brahmins and tulu pattars.
This was the clever ploy of varna system.Gurukkal castes will show savundi brahmins to dalits and will say "see we also do not allow savundi brahmins inside the sanctorium along with you.So this is not discrimination".
layer by layer,varna by varna this was oppression and discrimination. Oppressed himself was made to oppress people below him. Just like in dowry system where the mother in law asks for dowry and oppresses daughter in law. Here it is one female who oppresses another female.Here the mother in law forgets that she too was earlier oppressed by dowry system.
Just like how male chavunism turned a woman against another woman, varna system turned one caste against another caste.Only by this clever ploy, it was able to survive without much violence and upraisal for centuries.
