Congrats! You have successfully done a brigading! Pat yourself on the back! Next seminar, we will be covering how to subtly deceive strategically-important redditors with a simple tactic they don’t know of called ‘whataboutism’ 
Edit: meant to post this in the secret group chat where we coordinate the fall of the west. Sorry y’all. My bad 
Now you're starting to get it. Brigading isn't a thing. Brigading isn't a thing in old-school forums where raids are just a fact of life nor is it a thing on places like Twitter where getting dogpiled for being the Twitter main character of the day is just a fact of life.
Brigading is only a thing on Reddit, and last time I checked, we're not on Reddit.
Brigading is good actually. It's just another word for organised protest.
