Please read my post again. It clearly states FX eq full frame, and DX eq crop.
Current EF lens will mount to current Canon bodies, FF and i crop, except mirrorless, which require an adapter.

Define current. Try to put a Canon EF lens on an EOS 80D, or a 20D thru 70D.
No need to read your post again...
Here are your words: "In the Nikon world, FX is referred to as Full Frame, DX is referred to as Crop Sensor."
Full frame is referred to as FX and crop whatever is referred to as DX. See what I'm saying. The references are reversed, so, it actually doesn't clearly state what you say it clearly does. Remember William Clinton and the whole is thing. Take the is and as away and make referred to refers and you will have said what you meant.

In the Nikon world, FX and full frame are interchangeable, as are DX and crop. Semantics, as another poster pointed out.
And I am pleased that you realize there is no crop body available that approaches the 5D S family of Canon bodies. Please take note that I omitted the “/“, so as not to confuse any readers of my post.u😎😎😎

Can you elaborate on that a little, RE … the D500 is a 20MP APS-C camera, whereas, the D850 is a 46MP FF camera … how is it possible the $2000 camera, works out to be as good as the $3300 camera?
If I were to mount a DA {'DA' is how Pentax denotes lenses designed for crop-sensor cameras} on a "FF" Pentax K-1, the camera will automatically switch to 'crop mode', and the normally 36mp camera will become a (4/9)*36 = 16mp camera - it will act as though it is an old K-7 or K-50. If someone were to mount a DX lens on a "FF" D8500 and the camera switches to 'crop mode', the normally 45mp camera will become a (4/9)*45 = 20mp camera - it will act as though it is a D500.

I wasn't talking about total pixel count or overall physical sensor size either. I was talking about "putting pixels on subject" - because "crop sensor" pixels are typically smaller {again, the D850 and D500 are an exception to this rule because D850 pixels are roughly the same size as D500 pixels} - a given bird will be represented by more pixels if I photograph it using a 300mm lens on my 24mp "APS" KP than if I photograph it from the same spot using that same {or any other} 300mm lens on a 36mp "FF" K-1. As I said above, the K-1 acts like a (4/9)*36 = 16mp "crop" camera, so the KP will put roughly 24/16 = 1.5 times as many pixels on a given subject when using the same lens from the same spot.But that's not what I was talking about. I have crop sensor cameras with the same or similar pixel count as my EOS 5DSr. The crop sensor pixels are simply smaller.
I was talking about physical sensor size.

People will argue this point endlessly. If I mount a 300mm lens on my KP I see the same thing in my viewfinder that someone would see in the viewfinder of a K-1 with a 450mm lens. I choose to use the word "magnify" to describe that phenomenon - you may use whatever word you choose. If I take a photograph with a 300mm lens mounted on my 24mp KP, and someone else took the same photo with a 36mp K-1, then cropped to get the same number of pixels I got, s/he would have needed to use a 367mm lens (*). I choose to use the word "magnification" to describe that phenomenon - you may use whatever word you choose.All I'm trying to say is, crop sensors do not magnify the image. That's not what crop means. It's simply a portion of the image a full frame sensor would produce. And it all is dependent on the lens you use.
(*) to compensate for the fact that my pixels are smaller.

What does that even mean? Since when does DX mean half frame?!

I'm beginning to regret asking the question in the first place.

But, NO 7D2, huh, R … which is Canon's current APS-C equivalent to the D500 … 
Technically no! APS-C is a film designation for the now obsolete Advanced Photo System - Classic. One of the 3 APS formats. There really is no APS-C in the digital camera world and those who continue to use the term to for crop sensor cameras are basically, incorrect. Actually, all 3 APS formats were cropped.
I don't know what you mean by, but, no 7D2. The 7D2 is an older but also current Canon top of the line crop sensor DSLR. The newer D500 is Nikon's top of the line crop sensor DSLR. The 7DII was not and is not Canon's equivalent to the D500 because it predates the D500 by a few years. I do own both cameras.

You may choose whatever words you want. It doesn't necessarily make it correct. Sensors do not magnify an image. I don't really care if you believe me or not. I know I'm correct and that's all that matters.

That is all semantics. For any given FF lens on both, the SOOC image from an APS-C appears as a crop of the image of a FF. True, nobody cropped anything, but the APS-C sensor SAW a cropped portion of the projected image out of the lens, hence, we call an APS-C camera a crop camera.
You may call it whatever. ALL APS formats were cropped, all of them. The C does not stand for cropped. Why call a crop sensor APS-C? Why not simply call it what it is and leave the obsolete APS film cartridges dead in the past where they belong. What's easier, saying or writing A P S dash C or CROP. I vote for crop, a simple easy to pronounce 4 letter word.
There really is no place for the obsolete term APS-C in digital photography.

Ah, I see, R … I thought you'd replied to the wrong guy with that comment, and so I went looking for the guy who HAD said FX was crop, and DX was FF … I get you now … it's a matter of semantics …

In the misty past of the film era, Leica, Olympus and other companies made 35mm cameras with an 18x24mm negative size or half the 24x36mm negative of the full frame camera. Hence the DX format of 16x24mm is the digital equivalent of the half frame camera.

APS-C - area-wise - is two thirds the size of FF (area-wise) - so, I don't know how you can call it - half-frame
