Perhaps a little too far, as in ridiculously so.
Just about everyone I've encountered, and especially on this site of no-I-ain't-a-white-supremacist-buuuut... ignoramuses, think Indians are Negroids, not Caucasoids, till she got the VP nomination. That also includes SJWs (I've had to educate many on this here in the past). So such efforts would be purposeless. Heck, y'all even think Middle Easterners and folks from the Caucasus Mountains themselves are African.
Also, Africans have bigger, rounder - often bulging foreheads.
Further, "scalp reductions to make her forehead appear smaller" would be counter productive - in two ways: 1.) It would make her look LESS African if anything, except that 2.) a scalp reduction would make her SCALP appear SMALLER and thus her forehead look bigger because math.
Wearing her hair natural would be kinda sightly more effective a lot as well as simpler and cheaper (no more expensive hair straightening at the parlor), no scapels required.
Good grief, why must racism always be so ultra idiotic? Put a little elbow grease into it.
