I can't tell if you're intentionally misconstruing here, but assuming you're not - you would not be in a position of explaining to Spanish people why they are wrong and are really one thing or another (Also I assume you mean hispanic people, or Spanish-speaking people?) You'd be explaining the reasoning behind the modern use of the term, and allowing them to decide for themselves how to engage with it. The idea isn't to design a new armband that you require people of a particular group to wear each week - the idea is to ask those people what they want, and then respect them when they answer you. If someone says they identify as Latinx, then you identify them as Latinx. It doesn't have to be any more complicated than that. It's not about the enforcement of identity, *it's about the deconstruction of traditionally enforced identities in the first place*, it's about exploring the creation of new identities outside of the bounds of conservative tradition.
