Are polytheists the same as disbelievers?

[miracle114]

Salaam
So I read Br Joseph's article about other religions/creeds and although it does make sense about souls being judged based on their level of understanding  state of heart, faculties etc etc the fact still remains that polytheists are still attributing God qualities to false deities.
The Quran does say that everyone has been given their own way and that those with no Knowledge are not the same as outright rejectors and I can't help but imagine what will become of these polytheists with no knowledge.
Sometimes I do wonder if these souls are actually a test for believers only and that they are actually not being tested at all because come judgement day they may go back to a state which was before this life 
I am a "revert/convert" and would like to hear views on this as it does concern about the end of my non believer family members.

Jzk And peace
