Reddit reviews How to Win Every Argument: The Use and Abuse of Logic

I think you should know better than to assume the Internet is a window into reality rather than a frame into the individual creators mind. People acting wildly get clicks. People being outrageous get attention. Like a car on fire in the street, we are fixated by potential threats. Your own behavior is unfortunately the result of this mediated environment, and it's more unfortunate still that somewhere it is being recorded.

May I suggest a few books?

Give those three a try and let me know when you're finished.

Well, I'm certainly not an Economist^tm by any stretch, but I'll check it out. I've seen some of the conversations on those subs linked from here or SLS, and I hardly even know where to begin to address the questions, and I hang my head in shame because it's the same kind of infantile sophistry I used to throw at people. Seems like I'm not the only one who read this book.

I have a better one

NTA. But I recommend not to do this.

You are 19 now. But once you grow older, all that teasing will be insignificant compared to the shit that you will face that is being a man in the real world.

Here's what I recommend you do. Get a copy of this book and start to read it regularly. And use the techniques presented in it and use it back at your sister. Tease her, mock her relentlessly for sometime and once she gets sick of it, get yourself a ceasefire and tell her to cut off her bullshit teasing.
