There is nothing to know about gender identity because it is arbitrary and irrelevant. If a person would like to be called something other than what they appear to be then fine. That is an agreement you can figure out with that individual.

No. You don’t usually tell someone you are a man... because it’s obvious. Which is the whole point of the comment. Stating your gender or sex if they are somehow different is not something that people do (have done in the past typically)
