Das is pro theocracy.

But rather Hindutva is secular concept as nation and race or ethinic nationalism is worldly or secular thing.

If Hindus are exploited then it more due to weakness of Hindus and not only outsider but insider pseudo seculars also exploit Hindus.Thats is the mani reason of most the question you have rasied.

Coming to Christians and Muslims agreeing to savlation of non Belivers then the answer is big YES.

in Chirsitans we have orthodox like Greeks,Marthomities,Abisinains,Syrainas and some in Cathlocis also try to push in vetican that other faiths are part of plan for slavation of man.Problem is with protestants and counter protestant catholics.

Then in Islam we have Shias with Ahle Bait,and Sunnis with Ruh Al Kuddus mentailtiy.

Das just wants to put one thing here that spritual minded Muslims may help us against hell worthy Jehadis.
In Past main reason for Sikh ruling Muslim majority Area and Conquering Afghans etc. was more due to the help prvided by Muslims themselves as often Communal minded fundmentialist person may try to bully fellow religeon man.Say Aurangzeeb did prosecuted sufis(Like Hazrat Sarmad Rahmat ul Alhe),Shias,Bohras among others and they also did help Hindus or Sikhs.both in Army of Guru Ji and Chhtrapati we had Muslim soldiers.Only difernt was that Muslims in Guru Jis arym became Sikhs more so while in Hindu Pad Padshahi due to secular nature did not tgried to convert them.thats also OK.
