I am wary and distrustful of anything to do with flags or nationalism in any form. Most of it is a bunch of hyper-masculine prick-waving, designed to keep a somnambulant public from questioning their masters, tossing about largely empty and ill-defined notions like 'freedom' while playing up arrogance and cultural superiority as justification for all kinds of horrible things.
George Carlin nailed it when he reduced this to what it's really about by describing the Bigger Dick Foreign Policy Theory, which is best summed up as, "What? They have bigger dicks? Bomb them!" And as a corollary, "My god has a bigger dick than your god!"
You don't have to be an Angry Feminist Stereotype (tm) to see the illogical and ridiculous truth of this.
