What I see is a lot of pride and self-righteousness when christians blatantly criticize and judge other christians. They often will point to how Jesus got angry in the temple (Matthew 21:12-13), but that is not an excuse or a license to treat others with rudeness or insensitivity. Jesus is God and can judge all he wants.
We are not God. We are supposed to follow Paul's description of love towards each other (love is patient, love is KIND..it is not proud, etc...)
Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.
(1 Corinthians 13:4-7 NIV)
“A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples, if you love one another.”
(John 13:34-35 NIV)
