I really liked this post. For anyone reading the comments who wants to look up the etymology of words, I have found The Online Etymological Dictionary quite useful.

One of the most interesting terms in today's political climate is the verb 'discriminate', which originally was a neutral term for distinguishing between two things. Only in 1866 did it begin to be used in a negative sense to describe a negatively biased cognitive process. Curiously, 'discriminating taste' is still a positive thing. These kind of interesting facts that allow us to better understand the words we use is why etymology is so important, and fun!
