Judgmental

Oddly enough, people with good judgment are not usually considered judgmental. Judgmental is a negative word to describe someone who often rushes to judgment without reason.

The adjective judgmental describes someone who forms lots of opinions — usually harsh or critical ones — about lots of people. Judgmental types are not open-minded or easygoing. Judgmental has the word judge at its root, which itself is from the Latin word judicem, which also means "to judge." Judgemental (with an extra "e") is considered a legitimate variant spelling of judgmental

Why are people judgmental? Human nature cannot be denied. While good manners might prevent you from verbalizing your opinion, your mind instantly forms a judgment.
Everyone forms their judgments according to their life experiences. No matter how much you try, there are times you will make judgments. People like to think they are not “judging a book by its cover” but first impressions always bring about a judgment. You do it with out even knowing  you are doing it.  Children often mirror their parents opinions and judge accordingly. Some times if you over hear a conversation that has inaccurate information, you will judge the speaker as ignorant of the fact. I am judgmental of things no matter how hard I try to be fair. Some times it comes from being jealous. For instance a friend gets a new car. Or a new house.
The worst though are the ones who judge people who are less fortunate.  They assume they are all, lazy, welfare, illiterate, drug users, white trash, alcoholics, having illegitimate children to get more monies, laying around trying to beat the system.  I am sure there are those folks out there. In fact I know there are. But please don’t use that brush to paint everyone down on their luck as a loser.
