Relaxed Intensity
My personal way of looking at it is that a player only becomes a rules lawyer when they specifically only bring up the rules to make arguments that benefit them or the group, but do not speak up when the rules would actively hinder their efforts or the group's efforts. If someone speaks up whenever they think there is a gap between rules as implemented and rules as enumerated in good faith I consider them a rules stickler, which may or may not be an issue depending on the table.
