If anyone wants to really send a message, I know how to do it.
Every working republican/conservative American needs to take a minimum one week off work, all at the same time. Action like that would send ripples throughout the country at every level. Small gatherings do little more than sooth our own sense of obligation to do something, anything, and do not work to change anyone's mind. Let the rest of the country see just how much we contribute to society as a whole. When that contribution is temporarily suspended, an awakening just might occur (in some). The media couldn't, wouldn't be able to, ignore it. And the empty suits running the show would have to acknowledge it.
