I have been seeing these posts and videos making fun of Pakistani's for trying to claim Indus Valley and vedic heritage. Why the mockery? What is wrong with them claiming it? It is as much their heritage as it is ours. The "vedic" identity doesn't automatically associate with someone just because you are born on this side of the border. IVC is literally found in present day Pakistan,
Also, I am glad that those people are finally out of their cocoons (from thinking they are descendants from Middle East) to actually finally embracing their/ our heritage and civilisation.
Before 1947 neither separate India nor Pakistan existed, we were together, that heritage and civilisation are collectively ours.
So why this unnecessary fuss about them claiming this? What kind of weird insecurity our so called
"culturally rooted" people have that they are mocking someone for claiming what is equally theirs?
Why can't these dumb people realise that heritage and civilisation are not the same as religion?
