Zoroastrian Religion,Best of all

Zoroastrian Religion is the Best of all the other religions – so say the scriptures. Some Zoroastrians have written on other forum that Zoroastrians respect all alien religions among which is also Islam whose followers in Iran almost wiped us out and still call those left behind in Iran animals, after being called Dhimmies =infidels, for centuries. These writers who have written such were unable to give any scriptural evidences or citations from Avesta, Gathas and Pahlavi texts, all they have said that they have studied Hinduism , or one Dilip knows much about Hinduism. Why not follow Zarathsuhtra and study his religion, and if these people are right than Zarathustra is wrong as he said in the GATHA USHTAVAITI – Yasna 44.10 as follows
Tam daeenam yaa haatam vahishta
THIS RELIGION WHICH IS THE BEST FOR THOSE WHO EXIST
This is reflected in the Young Avesta which I suppose all those who believe in other religions pray Jasa Me Avabghe Mazda while doing kushti YA HAAITI NAAMAACHA BUSHYENTINAAMCHAA MAZISHTAACHA VAHISHTAACHA SRAESHTACHA YA AAHUIRISH ZARATHUSHTRIS THIS ZOROASTRIAN RELIGION FROM AHURA, OF ALL THE RELIGIONS THAT HAVE BEEN OR THAT SHALL BE, IS THE GREATEST, THE BEST AND THE LOFTIEST.
One can see easily see that this is NOT the narrow view of our religion as someone wrote. Why the scriptures are silent in saying that Zoroastrians respect all alien religions and pray in Mandirs, Mosques, Churches etc. as the path to god is the same while some followers can go to their god by killing people of other faiths as is written in their book and may get virgins in heaven.
As far as Hinduism/vedic religion is concerned Zarathsuhtra separated from Devayasna long time back and brought forth worship of one God Ahura Mazda Why Artaxerxes broke Devidana where idols of several gods were worshipped and built Apadana where Ahura Mazda the one God was worshipped. See also Dhalla -History of Zoroastrainsim where he wrote that CONQUERING PERSIAN ARMIES BROKE PLACES WHERE IDOLS WERE WORSHIPPED.
Parsis are free to worship Hindu idols, Muslim Darghas, study Hinduism and other beliefs as they please. Please note your views are your own but the truth remains the truth. No further discussion will be forth coming, please spare me a headache.
