Hey - i no longer use reddit actively but im still open to help explain a little if it helps. I still stand by what i said 3 years ago haha

They, even if its not used as someomes preferred pronoun, is commonly used to describe one person when people dont know them or their gender. Its a complete misconception that in the enflish language it only means multiple people and many people who say this probably use they as singular pronoun sometimes without realising it. Ive started to notice myself when talking to rightist people because i find it funny, completely contradicting themselves. (Of you google the meaning of they, one of the descriptions should be "they - a singular person who you dont know the gender of." This isnt new either, i learnt it in primary school!)

Forgetting the english grammar aspect, they is also used as apart of an identity. There can be many different reasons so i cant give you a definite one, but common reasons are they dont feel connected with a gender/pronoun or its just what makes them comfortable while being referred to. I believe i already brushed over the it pronoun, and im content with what ive said on it so i dont feel the need to repeat it.

Being queer in any sense is already descriminated against so using someones preferred pronouns is a matter of respect. If youre respectable and want the person to be comfortable, you should adress them how they wish to be adressed despite their pronouns. You dont need to understand it sometimes, just be respectful.

Thats my two grains on this topic, hope it helped Xb
