I believe that if you set Parental controls to on, it should get rid of most of the child-unfriendly stuff, including the sexism.
When playing using keyboard only, I always use the keypad, not the arrows. This way you can much easier use Pad7/Pad1 to aim, Pad9/Pad3 to look up/down and Pad5 to center the view. I think this is how it’s meant to be played on a keyboard-only setup.
