if killing people is the only way to fight this inequality then you should be out shooting. Are you afraid?
Everyone plays different parts. Some kill. Some help with policy. Some bring awareness in peaceful ways.
Killing isn't the only way... it's just effective in certain circumstances.
..... btw, others don't do sh1t; except get scared and let the fukkkery continue and pick apart the actions of those who do real actions. Those people play a part as well.
