Or, how about:
Don't make personal remarks about a woman's appearance - especially if those remarks contain the word "sexy" - unless you have a relationship with her that makes it appropriate, and unless the time and place are appropriate. 
And DON'T try to pass off sexually themed remarks to women as "compliments" - if she's a stranger, co-worker, or anyone other than a person with whom you have a close personal relationship. They are NOT compliments - they're creepy, demeaning, and unwelcome. In the workplace, they're usually meant to undermine a woman's authority. 
As to opening doors, how about doing that for anyone who is approaching a door you're going through? 
As to helping people who are being attacked, that's just to juvenile a whine to even dignify with a reply.
