From Breitbart:
Alexandria Ocasio-Cortez is proud of her roots but dont call her a Latina: she prefers the gender-neutral pronoun Latinx.
Latinx, as HuffPost explained in 2016, is the new, progressive way to refer to people of Latin American descent, replacing the traditional -o or -a for male or female, respectively
Latinx is the gender-neutral alternative to Latino, Latina and even Latin@. Used by scholars, activists and an increasing number of journalists, Latinx is quickly gaining popularity among the general public. Its part of a linguistic revolution that aims to move beyond gender binaries and is inclusive of the intersecting identities of Latin American descendants. In addition to men and women from all racial backgrounds, Latinx also makes room for people who are trans, queer, agender, non-binary, gender non-conforming or gender fluid.
Wonderful, this is a turnoff to normal people.
