There is a fine line between complaining and open discussion of predations and spreading knowledge. Sometimes you cannot dissever the three. I came across a quote fromTolle....
To complain is always nonacceptance of what is. It invariably carries an unconscious negative charge. When you complain, you make yourself into a victim. When you speak out, you are in your power. So change the situation by taking action or by speaking out if necessary or possible; leave the situation or accept it. All else is madness.Eckhart Tolle
So Tolle is pointing out three courses of action; change the situation, leave the situation or accept the situation. I agree but not entirely. I would point out that complaining can be an integral part of changing and even eventually accepting the situation. Also, one can accept a situation and simultaneously change it, leave it or even accelerate/ strengthen it. It eventually comes down to this: If a situation is morally intolerable, we can accept that it exists but spread the word about it's workings to our fellows (which is an attempt to change it through education) while realizing that the point has been reached when the situation cannot be escaped by fleeing it. There is nowhere to run. Sometimes one or society as a whole is a victim and that cannot be denied nor changed by acceptance. We may as well complain and point out the intolerable conditions that these world destroyers have foisted upon humanity as they largely point to us as the perpetrators of what they themselves are culpable for.
