I don't know very many people who say it isn't possible to "warp" a rotor (defined: bend or twist it out of shape). But such a feat would require immense heat and/or forces. The issue with the term is that 99% of the people that claim they have "warped rotors" actually just have uneven pad deposits or other rotor surface imperfections.
I might even still argue that if you can fix it with a lathe, is it really a "warped" rotor? Using a lathe indicates you can restore it to the right shape by simply shaving off the high points. A truly warped rotor would have a misshaped structure altogether (it would be twisted or bent), not just on the rotor surface.
