if someone wants me to specifically refer to them a latinx, ill comply. I dont see it getting any traction outside of this niche as an acceptable genderneutral form of declination. Latine fits better, since a lot more spanisch paradigms end on -e, from a linguistical standpoint. -x, i.e. /ks/ or /eks/ is very unusual according to Spanisch Phonology. And the vast majority of speakers will use the phonetically easier version, if they wish to change their speech patterns at all.
