Dude soad you nailed it, but in my view of the song "Anti depressents, controlling tools of your system" the depressents are the government making us believe in the idea of true democracy when in reality the companies in charge of voting have their own agenda for the country, the system is the voting offices witholding their information for fear of knowledge.
As for the beggining it's like the government telling activists' that their democracy is right and ours is wrong
the part in the begging "We don't need your democracy.
Execute them kindly for me.
Take them by their filthy nostrils.
Put them up in doggy hostels. "
the first line is the government telling us that their democracy is right and our's is wrong
the second line goes back to the "red scare" where "communist" citizens were arrested and had their life stolen away from them which basically goes witht the third and fourth line.
