I think throwing in an occasional quote from the founders might be beneficial. Such as:
"Perhaps it is a universal truth that the loss of liberty at home is charged to provisions against danger, real or pretended, from abroad" - James Madison
"Every law is an infraction of liberty. A long habit of not thinking a thing wrong gives it a superficial appearance of being right". -Thomas Paine
"They who can up give essential liberty to obtain a little temporary safety deserve neither liberty nor safety" - Benjamin Franklin
"Don't interfere with anything in the Constitution. That must be maintained, for it is the only safeguard of our liberties" - Abraham Lincoln
"Perfect freedom is as necessary to the health and vigor of commerce as it is to the health and vigor of citizenship". - Patrick Henry
"The greatest dangers to liberty lurk in the insidious encroachment by men of zeal, well meaning but without understanding". - Louis D. Brandeis
This next one is a little long, but really good,
"Whatever is the cause of taxes to a nation becomes also the means of revenue to a government. Every war terminates with an addition of taxes, and consequently with an addition of revenue; and in any event of war, in the manner they are commenced and concluded, the power and interest of governments are increased. War, therefore, from its productiveness, as it easily furnishes the pretense of necessity for taxes and appointments to places and offices, becomes the principal part of the system of old governments to uphold the system of war, and betray the motives upon which they act." – Thomas Paine in “The Rights Of Man.”
