Condemn, Protest… Lunacy

We are all smart people who care about our country and its people. Yet there are very few ways we can express opinion in way that matters. I have always spoken out about things are unfair but is that enough?

What more can i do?
Do i go on streets and protest?
Do i form a group which over time might have some political influence?

At this moment i am not sure, all i know is “If i cant do anything about things like this” then i have no right to cry.
