I should add, in my younger years I was very vocal and dogmatic with people. Very little compassion. I was young and ignorant. Thankfully most people showed me grace and didn't drive me into the ground. I think many of us, if we are honest will admit we have been like some of these people you are pointing out. Its fine and healthy to point it out but the way forward is to set an example by conducting ourselves as we would like others to conduct themselves.
