You do know that Miss Martian is hiding her White Martian heritage because of the racial discrimination and wars happening on Mars at the moment. White Martians are seen as savage, ugly creatures that are below the 'perfect' Green Martians. If you need proof/clues of this, a white Martian appears in M'gann's memories during her restoration of Superboy's memories in Bereft (very very quick scene near the start of the montage, and then in Targets she talks about the white Martians (and isn't very good at covering things up because she's like "BUT I'M A GREEN MARTIAN SO ITS ALL COOL")

As for Artemis, her father is actually Sportsmaster and is most likely serving as his inside informant. However, we don't know if she is willingly giving information to Sportsmaster or if she doesn't know that her father has a villainous alter-ego and is harmless just talking about her team with her father. Her connection with Cheshire may be more personal than believed considering both Cheshire and Artemis's mother share the same racial background (Vietnamese)
