It's weird how some words have so much power behind them. I could be killed for saying a certain word in a certain place. ******, faggot, cunt.. all such strong words. If I said "I'm gonna kill you".. whatever If I said "You cunt, I'm gonna crucify you!" then watch out.. I wonder if we'll have to invent new words after awhile.
Yet none have the power of a look or touch, hell I'd even go so far as to say a grunt or scream can carry more than a word.
I wouldn't consider those words powerful--just offensive. Power is tangible... words, not so much. And yes, we'll always add new words. Language is a living thing as much as the people who speak it. Bling bling
