Why is being socially rejected a bad thing? Society, in general, is sick and needs to heal, but I'd rather it not traumatize and child I may yet have. Teaching them to seek, value, and cling to truth is far better than any sort of acceptance that they may find if you let them be traumatized enough to fit in with the idiocy foisted on so many.
As an adult, I am fine with being outside of "normal" societal beliefs, but what will life be like for a 10 or 15 year-old who believes an alternate storyline?
Just fine if you also raise them to be resilient and also work to ensure that they know how to be generally sociable and also ensure that they have at least one like-minded friend in the community of people you choose to associate with. Yes, that means you have more work to do and more consideration to put into things, but, that's your purpose, so do it.
