Discrimination based on qualities that we like and dislike, agree and disagree with...

While we often complain about others for being discriminative or racist, but how many of us will show special liking and interest towards people who seem to be 'nice' and 'smart', who treat us the way that we like them to treat us, who have 'pretty' face and 'well-shaped' body figure, and we will treat them differently from those who seem to be 'not very nice' and 'not very smart', who don't treat us the way that we like them to treat us, who don't have 'pretty' face or 'well-shaped' body figure?

As this is also being discriminative.
