She mentioned the discrimination of being a Spanish speaker ( she is a Spanish speaker though)
She isn't. She may speak Spanish, but she's a native English speaker and has no trace of a Spanish accent (how could she?) There's no way the fact that she speaks Spanish as a foreign language means she's shared in the discrimination faced by many Hispanics in America. It's ridiculous to suggest this.
Mumsnetters have given her the identity of a Wasp but that isn’t the identity she wants, and it might not even be accurate. It also has negative connotations. White Americans don’t like the negative associations of being white so they tend to lump those associations with being ‘anglo saxon’
You're making it sound as though 'identity' is something you pick off the supermarket shelf, like a hair colour. Oh, I don't FEEL like a brunette, so maybe Light Golden Blonde? Then again, blondeness can have negative 'dumb' connotations, so how about auburn instead?
Joe Biden may choose to exaggerate his Irish 'roots' and play down his English ones, but at least he does have some Irish ancestry. So it really isn't the same thing as creating a faux Spanish 'identity' to give yourself an 'edge' in the yoga teaching/Instagram influencing world. It really isn't.
