Now, I think it's easy to take this type of situations and overeact. The behavior Susan described is not appropriate. That said, I think there is a trend to classify any romantic behavior or advances as sexual assault and innpapropriate behavior. Nowadays I would have a very hard time asking a girl out at work. Is it really that crazy that you might meet a girl/guy you might want to date at work?
I have had 2 girls ask me out at work in the past 3 years. Both times I just wasn't interested and politely declined. No big deal. I have also had girls approach me in professional settings such as conferences and ask me for my number and invite me for drinks. Come on people, we are human, we are attracted to each other and it's ok to approach other people as long as we are respectful and have some common sense. Let's not pretend we are robots.
I think the pendulum is swinging too much to the other side at the moment. It's easy to just generalyze and overeact. The opinion I just expressed would be considered very controversial nowadays and I would not dare to utter it in my office. People overeacted to drugs in the 80s and initiated a "drug war" that resulted in 1000s of people to be incarcerated for no good reason and billions of dollars wasted. Let's try to learn something from the past.
