Judging a person without even know

Judging a person without even know them is worst then a blind person coz even the blind person can judge with get in touch personally and judging a person in silent without even talk to them is worst then the deaf person coz even the deaf can judge a person by the communicate thru' gesture so if you think that you don't know how to use this method to get to know a person then don't even try to judge coz you do more harm to yourself rather than to that person you judging.
