>The thing that has always perplexed me about "Latinx" is that the those pushing that formulation are grafting what is a Germanic language construction onto a Latin-based word.

To be fair, English is extremely accustomed to etymological chimeras. A large portion of it is made of Old French, Latin and to a lesser degree Greek stems with English and Norse affixes/suffixes. Which is a perfectly valid way to import words while preserving the overarching grammar.

The problem with Latinx specifically is that it's closer to a regular expression than English.
