This is a common strategy to appear like you’ve won an argument when you haven’t
There are many tricks people use to appear like they’ve won an argument without having to actually logically demonstrate why their position is correct, argumentum ad populum, accusing the other side of trolling. One particularly egregious example is to state something to the effect of “well if you’d researched the subject as much as I have you’d see why my position is correct” which often results in the other side backing down as it puts them in the possession of either having to redo all their research on your vague say so, or looking like lazy anti-intellectuals for refusing to do so
