Christians do a bigger unforgivable sin i.e shirk, they claim partners to The Almighty. A sin that is repeatedly admonished in the Quran and considered THE biggest sin in Islam. Hindus don't believe in God at all and believe their idols are their gods. So which is a bigger sin in your eyes? Following a false prophet or the ones who have shirk as a key tennet of their faith. So if you are ok with the Christians then why are you not OK with Qaidianis ? Why the double standards
The prophet always preferred taking counsel and advice in matters rather than dictate, specially when he didn't need to as he was guided by the Allah s.w.t himself. And maybe you would like to read about the treaty of najran the Prophet s.a.w made because of which Jews and Christians had the right to join the services of the state. They had the privilege of being consulted on important matters. They exercised the right to vote. Their opinions were thought on the administrative affairs of the state. Their is no greatest example of religious tolerance than our Prophets s.a.w
Even Abu Bakr as 1st Khalifah did not move against the openly declared false prophets and their armies of the time until such time they either wanted to attack the Muslims first or rebelled against Abu Bakrs rule.
Qaid e Azam Jinnah had qaidiyanis in his cabinet. Ch Zafarullah Khan who served as Pakistan's first foreign minister, now curse Qaid e Azam aswell
