I think its about rising against a corporation or something of the like.
Reasoning:
He says "We will be here all day, we'll stay here till its over" maybe referring to protesting. He also says "till the worlds out of sight" Possibly saying that they'll continue until they've lost sight of their goal. The third and fourth paragraph saying how this entity has tried to silence them as in "Hold their breath and watch me drown". I think the line "fading light through an open door" is the losing of hope from the protesters. The lines "Through the nights in the rain, through the time and the pain, we'll stand here and never fall" showing their determination. The lines "and then at the the end of it all, we will win, we will chant" showing their confidence in this endeavor.
