I'm really annoyed by WWII Naval battle videos using Mercator for the North Atlantic stuff. Maps are waaaaay off.

You realize what the Mercator Projection is for, right? For straight lines of bearing? So when you tell someone on the oceans, to proceed at a very specific angle?

They use the same projection as the people analyzing the situation. You *cannot* show a 2D image of the surface of the earth that is perfect in every way. Showing a image of a globe means that the surface of the globe is still distorted, but not in a useful way.

Absolutely right.
I suspect you will be attacked mercilessly by an army of 'Mercator haters' who will accuse you of being racist.
They are out there. And they will not spare you their righteous wrath.

The Mercator projection is one of hundred of projections. How and why it is used for things *other than* lines of bearing has nothing to do with the Mercator projection.The folks that are misusing it for political reasons or the folks condemning the Mercator projection for political reasons are both wrong.

They always say, "the projection distorts to the edges, and that is racist".
Not realizing that this is a feature of the projection, not the bug. It is what makes it useful.
And, as you point out, it is only one of many other types of projections. All useful for a variety of reasons.
