on at least one occasion, Abe Lincoln bullied an opponent to tears with ad hominem attacks.
This might sound a little but in highschool my history class had a facebook group for discussing the politics that came up from the readings and discussions for us to turn into essay bits and junk. We had a conservative weenie in there and while I was very far from being a raging communist or even a socialist the both of us got into it about healthcare laws and other bullshit which eventually just turned into me berating him for just straight up lying about the laws and policies, the fact that he read the entire obamacare law (LOL). Everyone fucking hated all of his shit I got so much praise from everyone in that group, including my future girlfriend. The only time debate was ever tangibly good for me.
Rule #1: do not be a communist
