RE: Gentlemen, we are outnumbered.

What they do is they send someone in who pretends to be part of a group to make outrages comments in order to ruin the reputation of the group they target. The police are known to do this in peaceful protest, they'll send some police officers in who dress up like violent anarchists who will stir up trouble so the police have an excuse to go in and start arresting people. When you see tons of outrages comments, my guess is that they'll mostly fakes.

COINTELPRO, alive and kicking in the 21st century. I believe you're right, for one very simple reason: they've done it too many times before. This is not some wild conspiracy; these exploits have long been known by people in underground communities, and the gov't has declassified much of it themselves due to the sunshine laws. The Internet is the perfect place to conduct such operations because you can be truly anonymous here.

That being said, I think the vast majority of these kinds of comments is just attention-seeking bullshit for which the authors get a chuckle at shocking and angering other readers. In other words, it's just trolling.
