I support this effort 100%, but... there's something a bit off about the messaging that I can't quite put my finger on. Perhaps "the day"? This is going to be a long haul, not like killing SOPA or some other bad bill. This system is entrenched, and has a lot of support. It's going to be a long fight, and it's going to be a slog. For those in the US, though, please do call your representatives.
* It's clearly going to take more than a day to achieve a positive outcome in a system that was established over many decades
* What happens when "the day" ends?
* Since the action is framed as "the day", this is how the media will report on it - including outcomes of the day. These outcomes, whatever they are, will be packaged with the day and thus more easily dismissed than, say, "the movement" (which continues to grow) or "the tide" (that is turning) or "the big cleanup" (which must be repeated regularly)
