Why are “most” Mormons so judgmental?

Exactly as the title says: my daughters in laws are Mormons and they are the most judgmental, hypercritical and racist people I’ve ever had the misfortune of being around. My ex-husband (not my daughter’s father) wasn’t the same race as me and when they found out they acted as if I had committed the biggest sin ever!!

They act like they want to help the less fortunate but make sure to let it be known what all they do for people even going so far as to make a Facebook post about it.

They have ALOT of money of look down on me because I don’t and even went as far as to text me and tell me to “get it together” when I forgot a picture to bring to a birthday party but I was working 16 hour days.

I could go on and on about the things these people have said and done to others but then they preach to be Godly and help others while they’re looking down on people they think are beneath them. Is this common for Mormons because it seems as if everyone in their temple are like this.
