What's your source for that David?Check section 11 in the rulebook:
Playing a card as an event: Mandatory Event cards, Home cards, Event cards, and some Response cards (but never Combat cards) may be played as events during a power’s impulse.
Section 6.1 earlier doesn't allow response card general abilities to be played:
Response Cards
Cards with the name of the card in blue and the word “Response” printed on them are Response cards. Response cards are playable as an event in the Action Phase during any player’s impulse (including your own). Play of a Response card interrupts a player’s impulse, a battle, or an Event card play. Players should allow a reasonable amount of time for play of a Response card by another player after each action, event, naval combat, or assault. Response cards can also be played for CP during a player’s impulse if a player does not wish to use the card’s special ability to interrupt another player.
I don't see anywhere that allows for general play of response cards as your turn. In HIS there were Response cards (Landsknechts, Swiss Mercenaries) that specificaly allowed you to play them as an Event (with no modification to the effect or requirement to do so, so if we were to expect a change in rules it should be explicit in the VQ rulebook somewhere.
