Because the use of they and them over he or she isn’t about the traditional/ standard English grammar. He’s using the terms to replace gender specific terms to communicate that he doesn’t subscribe to traditional gender.

Question, have you ever picked up on a same gender loving person, wanting to keep the identity of a person they were seeing as private but also wanted to avoid lying? In that situation they would say I was talking with them or I was out them or... they did such and such lol prior to this current rise of *in your face, lgbt promotion* anytime you heard a sexually suspect person use those vague terms it indicated they were referring to same gender ppl. With times changing the community is now making their lifestyle more normal and mainstream.

In short, don’t see this with grammatical eyes. See it as cultural play on words.
