If LGBTQ+ people want to use the term Latinx to refer to themselves, that's fine. But they don't get to make that decision for the 98% who are fine with "Latino" or "Latina."
There is already an established way to make this term non-gendered, either drop the gender suffix entirely Latin, or make it explicit by using Latine. Both are which are existing words in Spanish with an established meaning. Rather than use this, activists in the US decided to demand 640 million people change their language to appease those who don't even understand their language.
IMO, genders on objects without a sex are just non sensical and a legacy product of Roman Latin evolution. A simple -e suffix could potentially fix this, but it's incredibly hard to change without a generational change, cause language and habits are sticky. However if you are triggered by a table being female gendered or a car being male gendered, maybe you are overthinking it.
When it comes to human related words, another potential approach is to always use the female form, because you refer to the word person (la persona) and not the particular gender of the individual in question. This applies to groups too, the rule in Spanish is that if a group has females and males, you should use the "male" plural form. Why not just use the female form and everyone is happy?
Just remark that this is a hot topic and conservative and older people usually oppose this aggressively and openly. New generations understand the arbitrary split of society in two based on the presence of a penis more intrinsically though.
