One of my friends can't take any disagreement. If people don't think like her to 100 % she thinks they cannot be true friends. She is also an extreme detail thinker, I think this influences this behavior, that you can't accept one thing "wrong" with someone, it spoils everything sort of.

She tells me over and over what I should think. It gets a bit tiring.

For me it depends. I judge people quite harshly sometimes but mostly just in areas I think are extra important.
