Uh, no. Hinduism has completely separate gods. It's not really debatable unless you're talking sects, but then you could say Christianity is polytheistic because there are Christian sects that believe it.
Christianity is monotheistic.
If you somehow manage to twist words and cause people to believe you, you very well should run for governor.
Concept of God
Main article: God in Hinduism
Hinduism is a diverse system of thought with beliefs spanning monotheism, polytheism, panentheism, pantheism, monism, atheism, agnosticism, gnosticism among others;[69][70][71][72] and its concept of God is complex and depends upon each particular tradition and philosophy. It is sometimes referred to as henotheistic (i.e., involving devotion to a single god while accepting the existence of others), but any such term is an overgeneralization.[73]
As I said, Hinduism isn't easily explained. Out of the 4 major sects, 3 are monotheistic, the largest praying to Vishnu.
Edit:
Speak for yourself. Nearly every single argument you get into you lose. By this point you should always assume that whoever you're disagreeing with is right, because that's almost always the case. Whether the Hindu gods are all one or completely separate is not up for debate. They are separate, just like the ancient Greek and Egyptian gods.
You don't seem to know anything you're talking about there.
