Why bother getting pissed off over someone whose brain looks like the centre of a doughnut? You can't play violin to a hippo, so reasoning with such people is a waste of time.
Just for the record so I don't get reprimanded for being OT, events are PIS if they are obviously construed to attain a certain end, even if the reason is not plausible. Thanos' battle with odin was not PIS in any way. You cannot really say that Odin held back and did not want to kill the titan, because Gungnir says otherwise. With no plot devices or anything unreasonable happening, what PIS is there? Thanos blasted Galactus once, and got hammered for it. What PIS is there?
Oh, and Thanos wins, but after listening to the haters, Thanos wins, but the reasonable people here all lose.
