Thats funny, I guess you never know. Perhaps the whole movement is an afternoon tea party gone VERY wrong.
No I know what mean and the name does carry with it a certain image giving us clues to whats goin' down. The tea party does get thrown around a lot here by groups needing an identity against the powers that be and its meaning tends to get watered down to the point of sometimes just being a pointless slogan that sounds neat. Along the lines of "remember the Alamo" and slapping the rebel flag on a truck bumper the person or group using it may have no idea the real historical connotation behind it, again I have no idea why they choose it, just making conversation.
