@JeremyECrawford @SageAdviceDnD would a half drow using the rules from sword coast adventurers guide be able to take the drow high magic feat from xanathars guide?

The racial feats in Xanathar's Guide say which races qualify for them. Half-elves, for example, can take the two feats that include half-elf as a prerequisite. The SCAG's half-elf variant doesn't change how that works. #DnD https://t.co/o0ahUUAoKr

That being said, I don’t think this answered the original question. Mainly, is the half-drow able to take that dow feat? Even using the SCAG variant, a half-elf who is part drow and part human is still a half-elf, not an elf (drow) or a human.
