Assumption is the mother of all fuck-ups

First let me give credit to my Twitter friend @farhanmasood for the title of this blog post. Your tweet came to the precise moment. :)
We always make assumptions.
Jews - they run the world from backstage because they have loads of golden coins. Muslims - they are the leading terrorists because they are cruel and fanatic. Christians - they are bigots, because they go to church, but stab you behind your back. Hindus - they are weird, poor and they live among mice, because this is what we saw on a damn youtube vid.
Lawyers - they are sharks, because they dare put you in jail, after charging you big time. Politicians - they are corrupted because they build palaces with the money from the taxes you pay. Rockers and bikers - they are to be banned, because they worship Devil. Advertisers - they suck because they play with your mind. Homosexuals - they have to be punished because they are against the nature.
Says who? (sic!)
All of the above are pure assumptions built up in time due to unfortunate occurrences, prejudices and lack of knowledge and information.
On a smaller personal level we proceed in the same way. This colleague is stupid, because she/he cannot send a fax. She is a whore because she slept with several guys. He is an opportunist, because he offered himself to work more. She is a bitch, because she did not admire my new dress. He is a goof, because he married with the bitch in the previous sentence. He is a part of a conspiracy because he does not give you the same amount of attention.
Stop judging. Gather information. Know all the details. Check different sources. Wait and have patience. Do not make assumptions as you can get yourself in the most fucked-up situation.
Repairing the consequences and healing the wounds might cost you more than you have imagined.
