Whats wrong with that?
Well I say it's time we define ourselves . . .
You use words to describe something based upon what the word means, you do not change the word's meaning to fit what you are trying to describe.
Words change their meanings with time.
Just like 'Liberal' doesn't mean what it use to mean. Now it means collectivist, basically. And in this case, I'm not inventing anything -- one definition of 'Conservative' is 'careful'. As in 'conservative with money'.
I'm not changing the meaning of the word at all, therefore. I am using a 'different' word, or in fact a different description of the same word, to describe who and what we are.
I completely disagree with your premise, I'm afraid. Maybe it would be more helpful if I asked you . . . what solution would you propose? What words would best describe people who are 'politically' in favor of smaller govt and strong defense?
