That seems exactly backwards. If I have a strong preference for one side over the other, and I work to support the side I like, and I lose, I'm not allowed to complain, but if I have a strong preference for one side and do nothing about it then I am?
Complaining can also be legit if you don't vote, e.g. in cases where you are presented with a slate of candidates all of whom you hate equally.
