When all else fails they go through your history and find something they don't like which in their mind completely discredits your argument. It's that or they use all the debating terms like their some sort of renowned intellectual. "That's a slippery slope, false dichotomy, false equivalency, ad-hominem, strawman, red herring!". Mindless pseudo intellectual fluff regurgitated over and over again. Monkey see, monkey do on Reddit.
