Just wanted to add, because it wasn't in my earlier rant, that I strongly believe there is no such thing as "just a word"
Words have substance. They have weight. They are real, physical, things. You can take a word and put it on the table.
Words can start wars. They can wreck marriages. They can destroy friendships.
Words can lift spirits. They can pull a person from the brink of despair, the edge of death and back into living again. Words can bind two people together. Words can build a person up, they can forge the way for peace. They can transport you to a place that has only existed in another person's mind, and let you see a time, place and people that don't exist in our world. They are magic.
I believe that the words we use, the words we think, affect who we are. They can change us in subtle ways. Words are powerful, and we must use and choose them carefully.
