Neopronouns like ey/em, ze/zir, and xe/xem are much more convenient than they/them, since the fact that they're singular removes ambiguity about whether the pronoun refers to a single person or a group of people, and obviates the need for differing verb conjugations depending on the pronouns of the person being discussed.

(Third person pronouns, not pronouns like "you" or "I".)

Unfortunately, nobody can agree on which one to use, and it doesn't seem to be getting better.

If any large, reliable survey shows that at least 75% of nonbinary or otherwise gender non-conforming people who do not prefer he/him, she/her, they/them, or "no pronouns" choose the same option, this market resolves YES.
