Okay but, no, from even my rudimentary understanding of Spanish, feminine terms end with -a and masculine terms end with -o. Latino would then be masculine. Latinx includes latina, latino, and whatever the word could be for intersex and/or genderqueer people. Even if you want to ignore genderqueer and intersex people (in which case, go fuck yourself =) ) latinx covers men and women without lumping one group into the others gendered term and without wasting time and energy saying “Latino y Latina”.

And “folks” doesn’t have any connotation, or language-based reason for it to be gendered. No one is saying “folxs”.
