Look idiot, there was no such thing as Hindustan or the name Hindu in 3000 bc. These came into use only a few 100 years ago. If you think the people of IVC went around calling themselves Hindu or thought themselves as Hindustani you need your head examining boy.
Find me one source which proves yopur claim and I will apologize to you. Look boy live with the fact that the 95% of the IVC is in Pakistan. The centre of gravity of IVC was in Pakistan. It may have overlapped slightly into Afghanistan or India but it was central to Pakistan.
The Indus River is to Pakistan what Nile is to Egypt. There was no Pakistan in 3,000 bc but there was no India either in 3,000 bc. In fact 3,000 bc there was non of the countries that exist today.
Look boy for 5,000 years our land has evolved and guess what? We are the decendants of those people your worshipping. So I guess we should be enamored that your licking the balls of our forefathers in Pakistan.
So keep it up !!!
Ciao.
