Make me remember a conversation a guy claim he could easily went 2000 miles in one day, another response even at 70mph it would take more than a day, the guy just reply SOURCE? like some kind of trained reaction
There was a Russian guy I worked with once who was very argumentative and opinionated, but anytime he made a shitty point and you started to win the debate he would just say "that's a logical fallacy" and walk away, like he won the debate. He was difficult to be around.
Funnily enough, the guy refusing to give their bank details IS presenting poor arguments. Of course, this is assuming that both parties have consented to enter a debate. If this was indeed a debate, it would kinda delve into a debate over the objectivity/subjectivity of morality as a whole.
