Xorn was right about everything except the extreme sinophobia inherent to his character...but only if one accepts the original Morrison version of Xorn, where he is implied to be Magneto's conscience, instead of the current retconned Xorn who is more genocidal than Magneto

Oh jeez, don't get me started

It was a triple fakeout Real character>panic rewrite to absolve him of the unrecoverably awful shit the fornerly-real him did>third rewrite to make both "real warcrimer" Mag & "Xorn 'Mag'" into different guys.
