I scrolled through, not really reading, to see if Johnnyx had commented, since I believe he's the only native Spanish speaker on the board. I didn't see it.
I have a nonbinary native Spanish speaking friend on facebook and they said that gender neutral language in Spanish is being developed. x is sometimes used as a suffix (latinx) or e. Personally I prefer e because it is easier to pronounce. I believe there are other approaches, but those two are the most common.
