Prejudging can lead us to do the greatest blunders ever, differently from knowing  the cultures, believes and ideologies.
First, there are these people who can't separate religion from nationality often make stupid protests like the one we saw in the United States in which people were against the construction of a mosque in New York city.
Then, there is the ignorant notion that all homosexual people are promicuous which creates an erroneous idea since it's not about sexual orientation and it happens in homosexual relationships as much as in heterosexual.
And finally, there are also "blindfolded" people who advocates for parties that don't worry about their own stratum. They are so blinded by this idea that they can't even see what these parties do in a wrong way like buying votes and all that stuff.
For these reasons, I think people should read more about countries, history, social levels, religions and try to know and understant why people act the way they do and don't pre-conceptualize any subject or person.
