Conspiracy forums are filled with this behavior. Are both sides generally corrupt? Well, duh. Is the two-party system a false dichotomy? Undoubtedly.
It used to go the other way when "Republicans" were "in power" but now it's being used to deflect from Democrat corruption. If you point out the tyranny of Democrat politicians right now, you will often be swarmed with these bots/shills screaming about "muh two party" corruption etc. Nevermind it's the Democrats who are literally acting like fascists.
Just an observation. I know an astroturfed response when I see it.
Quality content.
I would add that another closely related shill behavior to this "both sides are corrupt" tactic is to use the "but Dems/GOP were in charge when the federal government did X, so they are just as guilty" tactic.
The federal bureaucracy is a lumbering leviathan, and if you think that the occasional switch of party control of one or both houses of Congress, or even the Executive Branch, changes things down at the deckplate level, well, you have a primitive understanding of how organizations work. The president says something, but often, nothing gets done if they bureaucrats don't want it done.
Congress only has control over the bureaucracy when they cut their funding. They can hold hearing after hearing and rant for the TV cameras (for example) at the IRS agents who should be in prison for going after Tea Party groups, but until they cut the funding or the IRS, they didn't really care much.
