How Can You Judge Who You Don't Know

I find it funny how people can judge you just by looking at you. what ever happen to the old saying "never judge a book by its cover".
How is that you can judge me & you have never had a conversation with me or taken the chance to get to know me. If you are that shallow that you judge a person by the way they look or where they live then you have a serious problem buddy. If you never take the time to get to know some one then your opinion about them means absolutely nothing. So before you judge me by the way I look, how I live my life or my sexuality at least take the time to get to know me. Beside only god has the right to pass judgement on some one
