Please don't make wild assumptions. This isn't a trial. There's no evidence or admittance of anything needed.

These are accepted grammar rules. "you guys" as a second-person plural term is accepted as gender-neutral. "guys" in the third-person is not.

Arguing that the 2nd-person usage is not neutral is the new challenger position and you would need to provide the argument for why the accepted usage should change for the rest of us.
