I don't think that's possible. The press pressure helps, but the reason companies go this way is they hire people who genuinely ARE activists and think this way. These people push their ideas, and everyone around them doesn't want to be rude to them, so it just escalates from there. The call is always coming from inside the building to some extent. You have to really scourge these people out and make them unfeel unwelcome, or they take over. By the time it reaches the point that it is visible in character creation and "male/female" sliders being unacceptable, the fight is already over.
