50mm x 1.6 = ~85mm (80 actually, but close enough)
Using a 50mm on APS-C is like using an 85mm on FF.
So your silly logic is silly

Now if you had said, "I think 35mm is a way better normal prime on crop", then I agree. I have both 30mm and 50mm f1.4 lenses and enjoy them both.
In fact, I did say that...
50mm on a crop is NOT like using an 85mm on a FF.
50mm on a crop for just taking photos? Get real. It's much too long and not wide enough. This is why it's odd on a crop. He's better with a 20, 24 or 35mm lens for "standard" shooting. Not a 50mm.
