are infps really open-minded?

I've always heard how infps are one of the most open minded but all (4) of infps i know are biased and quite judgemental. always gossiping and backbiting. 3 of them are conservative and dogmaticly religious. sure they have some things they have no strong opinion about but then again they can be very hypocritical. because when it comes to topic they have a strong opinion on they are very intolerant of different perspective, it becomes black and white for them.

no offense to infps, maybe i am wrong but i found all other type I've met more open minded as an intp compared to infps.
