There are people with strong beliefs and opinions they are ready to fight for - within the frame of their daily job, using their free time, their own money etc. All this without being enthralled to a "bigger entity", as a part of a conspiracy, serving a special interest playing power games, or simply someone paying them. I am one of those people, in agreement with this post, I can see the OP being in this category as well. If this is all too surprising for you that is a reflection on you.
