Canon doesnt seem to come in the picture in your defense of the New Mutants casting
For someone who "never really thought about it" until posters brought it up have gone outta your way to try and prove Blink is anything other than black. Despite the on panel evidence.
and I am well aware of her alleged family member. Even if Slade was her ancestor Im not sure what that proves. My grandpa was FOB Irish... like straight up potato eating, whiskey drinking, IRA hatin Irish. My grandma? Cree Indian with African ancestry but looked so light they avoided being charged with Miscegenation. My dad's pretty old but im sure was born less than hundred years before me. lol What Im getting at....claiming her ethnicity through an ancestor more than 120 years ago is silly. especially considering they moved to the Bahamas where its 90% black.
assumed does not make it Canon. It was assumed that Gambit was the 3rd Summers brother. It was assumed Hope Summers was a reincarnated Jean Grey.....none of those panned out.
