You want to know how to really contribute to the problem? Tell women that their co-workers, who will be largely male, are a horrible bunch of sexists who will mistreat them based on their gender. If they don't quit right there, teach them that any action those men take is a "microaggression" directed at them as a result of their gender. Teach them that the appropriate response to these "microaggressions" is to be extremely upset and angry, possibly to file a complaint with management or HR. Tell them (and convince HR) that a man defending himself from such a complaint is itself sexism and oppression. This will ensure the women always believe they are being oppressed, that they always feel uncomfortable, and that their male co-workers will never feel comfortable with them and will be apprehensive if they are anywhere around.
Then, once you've done this, blame the toxic environment you've created on male sexism. It's a positive feedback loop.
