I have been to Reddit close to five years now. I completely agree with what you wrote here. But may be as you are new to that sub you may not know what is wrong with it and why it is so biased, so let me tell you something.
There are paid trolls for AAP and now Congress. Before 2013 that sub was not infected by rabies but as soon as 2014 elections came closer AAP got its own shills. Rahulthewall was a moderator who actively claimed he was on payroll of AAP.
Then there is Kasif who openly declared his allegiance to AAP. Rahulthewall later on took off from his main alt and brought in by some other alt that we don’t know.
