Now we're getting to the crux of the matter. Just what did the Vedic people think of their own precursors, or at least, the original owners of subcontinental Hindu thought? Wikipedia:
"Later Vedic literature speaks of the western Anava tribes as mlecchas and occupying northern Punjab,
Sindh and eastern
Rajasthan. The tribes of the north were mlecchas either because they were located on the frontiers such as
Gandhara, Kashmira and Kambojas and therefore both their speech and culture had become contaminated and differed from that of Āryāvarta, or else, as in the case of southern India, they were once Aryas but having forsaken the Vedic rituals were regarded to mleccha status."
"The Indians referred to all alien cultures and races that were less civilized in ancient times as 'Mleccha'
[3] or
barbarians. Among the tribes termed Mleccha were
Sakas,
Hunas,
Yavanas,
Kambojas,
Pahlavas,
Bahlikas and
Rishikas.
[4] The
Amarakosha described the
Kiratas,
Khasas and
Pulindas as the Mleccha-jatis.
Indo-Greeks,
Scythians,
[5]and
Kushanas[6] were also mlecchas.
[7]"
Several of these tribes were heroically defeated by your boy Sudas btw.
So let's be honest with ourselves for a minute.
Indians have the gall and the wherewithal to condemn Pakistan for adopting some foreign culture, when:
1) Vedic Hinduism was formalised most probably by foreigners.
2) The very scriptures themselves speak of this new faith's defiance against the older and pre-existing canonical Hindu culture.
3) The native ancestry of this land is slandered as "mleccha" for daring to reject the imported teachings of migrants.
4) Even physical violence against these precursors is deemed appropriate to establish the newer faith as the only true variant.
Again, Islam, KARMA.
