Seriously? You're all just a bunch of cis-gendered #&*(-lords.
CLEARLY this is an example of the patriarchy in action and this poor deluded woman (the wife, not the heroic mistress who stood up to racism) is aiding her oppressors.
The judge wanted to make sure that mistresses know they not only need to keep the husband happy to keep what they have, but they have to keep the wife in the dark/happy.
This is all a tool for further oppression of teh wymynzes!
