Is anyone arguing that?Anyone arguing that darkvision is a disadvantage to see through magical darkness and it's easier to see through magical darkness if you don't have darkvision, is either arguing in bad faith or so deep in the forest that that don't even realize those are trees around them.
Seriously, I think the #1 hint as to how this works is the name of the spell.
