I think we all realize how words can affect us, from the words we use to the words we hear and read from everyone else. The PC notion was started with good intentions- to reduce the sexism and racism that was present in some of the everyday language that was common. No, "man" does not mean human anymore than "woman" does. Specific words hold strong distinctions that can affect us subconsciously, though the entire notion has gotten extremely out of hand. Merry Christmas!
But, I found out recently that even the letters we are attracted to are letters than have significance to us. The initials of our names create a preference for words that start with those letters. This has been found even in GPAs, with people with names starting with A and B getting better grades than people with names starting with C and D. People choose their brands with a preference for ones that start with their initial letters. Since reading that, I've noticed how many of the brands I'm loyal to start with an S- there are a lot.
That's how deeply words can affect us. We see the words around us as being personal and connected to us, even when we don't realize it.
