I wanted to know your stand on the issue. Do you think that there should be a law against people spraying or carrying perfumes in schools? No, because that's just a very short step away from legislating what kind of hairstyles people can have, what kind of clothes they must wear, what they can read, and so on.
What I DO think is:
(a) people of both genders need to use common sense and good judgement as to when it's appropriate to wear scent and when it's not;
(b) nobody should ever take a bath in the stuff;
(c) if a co-worker or fellow student finds the scent is overpowering and/or it causes them a problem of some sort, they should courteously mention that to the wearer who should just as courteously thank then for informing them and immediately cease wearing the objectionable cologne in that venue;
(d) if scent causes someone genuine health problems (asthma, migrane headaches) and the co-worker or student refuses to refrain from wearing the scent, then the employer or school needs to get involved and possibly mandate that the scent not be worn as a reasonable accoommodation to the co-worker or student with a problem.
earthgirl, I'm not sure your paper is going to have a lot of substance to it. Other than the ADA angle (which isn't all that much), the rest of your paper will be no more than random opinions on the topic.
