The parties on both sides of the Rice/Dropbox debate have good arguments:
* Ms. Rice has been a very important representative of a US administration that caused a lot of people to die in Iraq and elsewhere;
* but she is not the only one in the government of that day, and many other (non-bullied) politicians are complicit as well;
* and the current president has not shown much anti-torture sympathies either, yet him being branded a Democrat makes him much less of a target.
I believe channeling energy to make Ms. Rice leave Dropbox solves nothing. Channeling the same outrage to make the elective system into a non-money-based race, to make the politicians accountable for what they promise before elections -- that may solve something.
As a non-American, stating an opinion is about all I can help you with. Good luck!
