Freedom is, by definition, the absence of necessity, coercion, or constraint in choice or action. Freedom is defined as liberation from slavery or restraint or from the power of another.
Government, by definition, exercises continuous sovereign authority & control over its subjects.
Therefore, freedom can also be defined as absence of government.
The less government we have, the more freedom we have. These two things are directly related. (note, I didn’t say zero government, just less. Much, much less. See Peter Schiff for more on small government.)
Ask yourself, if you back the expansion of government, what are you really in favor of?
