I can't stand "THEM"
That I hate the use of "them" to refer to anyone that is transgendered or just not cis. Every time I read an article about "them" I'm never sure if the writer is referring to one person or a bunch of people. The difference between singular and plural is important. Without the distinction how do you know how many people you are talking about? Why not create a whole new word or use "one".
Way back when I was a student I was so annoyed at the ridiculous number of female identifiers (Ms, Miss, Mrs) that I just stopped using them entirely, along with unnecessary gender identifiers (not related to the subject matter), and it didn't take me long to adapt. "Them" I just can't seem to adapt to. I'm probably overreacting, but damn does it ever irritate me.
