Therein lies the difference between "This is what I believe." vs "This is what I believe, and anyone who isn't actively fighting for my cause must be evil." None of us here can really know what Brian has done as a private citizen in terms of political activism. What would you think if he is privately active (maybe even for causes you agree with!) and also chooses the workplace to be politically neutral?
(Speaking of which, what have you done to fight the status quo? Why not more? Why have you not consumed all of your time/money/attention on it? What level is necessary to be considered not-complicit in the status quo?)
