Isn't calling C the speed of light in e=mc2 misleading as light is a specific part of the electromagnetic radiation spectrum.

Shouldn't C be the speed ot the electromagnetic radiation spectrum

Since all forms of electromagnetic radiation have the same speed in a vacuum, calling 'c' the speed of light is OK. Often all wavelengths, not just the visible, are referred to as 'light'.

Right so then there would also be no objection to calling C the speed of gamma, or speed of infrared?

Sure. No problem. All the same. Just calling it the 'speed of light' is more generic, though.
