I totally agree with you, in the last sentence you have placed.
It is normal in the human being, we make mistakes but we must learn to stop that mania of judging without knowing.
It has happened to me many times, and then I apologize because it is wrong, and I see that I have errors that I must correct.
The Bible says in Luke 6:37. And judge not, and ye shall not be judged: and condemn not, and ye shall not be condemned: release, and ye shall be released.
