Personally, I find it distasteful to default to "man" when referring to people that you're unsure of the pronouns of, especially those that are seemingly female presenting. This is an example in choosing your battles, because nitpicking someone detracts from their point. Pettifogging and such.

Furthermore, I think the number of sentences in your reply is entertaining, for someone criticizing another for spending too much time on this app. Also yes I am indeed pettifogging. =^}
