4chan, specifically /b/, inspires within me many emotions. Fear, pride, anger, joy, among others. However, whenever I see something with the title "4chan declares war..." I proceed to shit bricks, followed by actual feces, followed by most of my organs as they attempt to flee the grasp of The Internet as quickly as possible.
They may not be the best ambassadors the Internet has ever had, but when they believe in something, by the gods, do not stand in their way for they will destroy you and everything you hold dear.
No matter whether or not I've agreed with who they've launched attacks on before, I've always stood in awe at how quickly "not your personal army" can mobilize, assault, and reap the reward.
