There's wading in water, there's treading in water, there's snorkeling, there's diving, there's standing on a boat, there's drifting aimlessly. They are all different ways of interacting with depth.

If you have a problem with the extent to which I've represented my knowledge and how my representation of those specific things I discuss differs from how experts deal with them, you are always free to provide something beyond snark and contempt.
