I would offer requiring everyone to think like me is a greater cause of division.I would offer that we need to let go of the word Trinity, as that doctrine has become a cause of great division amongst humanity.
You think I am wrong / I think you are wrong / And, as Vonnegut says, 'so it goes'.

I would assume, once you've rolled-up Trinitarian Christianity, that the object of attention will be the next doctrine down the line, that eventually Judaism, Islam, Buddhism, Hinduism, etc., will be obliged to let go of the core doctrines that don't fit your model or accept your governance.

Better, all round, I would have thought, we agree to live and let live, and delight in the different ways of coming to 'It'.
