When You Find A Person Who Prefers To Be Referred To As “They”

Luke 8:30-35 KJV
And Jesus asked him, saying, What is thy name? And he said, Legion: because many devils were entered into him. [31] And they besought him that he would not command them to go out into the deep. [32] And there was there an herd of many swine feeding on the mountain: and they besought him that he would suffer them to enter into them. And he suffered them. [33] Then went the devils out of the man, and entered into the swine: and the herd ran violently down a steep place into the lake, and were choked. [34] When they that fed them saw what was done, they fled, and went and told it in the city and in the country. [35] Then they went out to see what was done; and came to Jesus, and found the man, out of whom the devils were departed, sitting at the feet of Jesus, clothed, and in his right mind: and they were afraid.
PS: Legion means “Many.”
