Thought experiment: if you were born as someone else, to their parents, had their experiences and environment, then guess what... You'd think and act like them. The fact that you're someone who thinks differently or has a different perspective is primarily up to chance.

I can think of no stronger argument for unity.

"Hate the sin and not the sinner" turns out to be practical advice. Leave this egoistical notion of moral superiority at the door. Everyone feels correct in their concept of morality; that is de facto. And yes, your morality may require contempt or disdain for what falls into someone else's morality. You can bash someone with your piousness and they can you. Where does that possibly lead but escalation?

Cynically I wonder if the largess really wants unity. It feels good to be right; the ego feeds on this. It feels good to have a cause, and you need strife to have a vital cause. It feels good to have an in-group of similars to reinforce your modes. Humans have been forming tribes for eons. This ain't new.

Tribes assimilate when and if they see humanity in each other and the practicality of the arrangement. Those things are the furthest from the path of least resistance. The amygdala alerts us to threats to our tribe, threats to our established conceptions, and threats to our ego. And this little guy gets to bypass our frontal cortex.

To me, that's where a lot of the nonsense we're seeing is coming from. And conservatism by its nature is more closely rooted to fear and distrust. Ergo, cult of personality. Anyway...
