@lurker123 because words have meaning behind them. If I say that you are "faggot" or "all jews and gypsies should be killed" and then go "well, it's not what I actually meant. I just used wrong words" it would be just stupid.
My dude, I wish even half the internet used memes and words with consideration to their original meaning, context and application. Some claim the whole "progress of language" but its bullshit when its actually regressing.
