Anyone else annoyed (to the point of having your gizzard chapped *heh*) by speakers and especially by writers who use the plural pronouns, “them, they, their” in place of “he or she, him or her, his or hers” whenever they simply want to obscure–or simply not specify–the sex of the (singular!) person to whom they refer?
I view such usage as lazy and cowardly. Use gendered pronouns whenever possible. Chap idiots’ gizzards.
