Can men be victims of sexism in the United States?  If they can then
in what circumstances or conditions does this occur?  If they cannot,
why not and what factors make this condition impossible?

Is there any sociolgical research out there in regards to this
question?  I'm looking for published articles, preferably from a
sociologist or someone attached to a university or some other
reputable organisation.

Thanks

One place to look is gender-specific dress codes.  For example,
requiring one gender to wear a necktie, and the other not.

Another place to look would be men applying for positions where women
are more often hired.  For example, hostess, receptionist, maid, and
nurse.  Or conversely, are men who are uncomfortable performing tasks
commonly assigned to men, like "lifting" or "warehouse" work mocked
for not being "man enough" for the job.

That's just in the workplace.

More broadly, gender norms that are so commonly accepted as to become
sexist, can effect both genders.  While behavioral expectations are in
a constant state of flux, there are still expectations for the role of
the man in courting rituals (example:  paying the check), marriage
rituals (example:  proposing), and household rituals (examples:
repairing the dwelling, fixing the car, and earning the only or larger
paycheck).

Another place to look is how the legal system treats gender issues in
custody and divorce proceedings.

You might want to look at the literature on Men's Studies... this
might get you started:

One of Messner's books:
Taking the Field: Women, Men, and Sports

Snapanswer,

The Highbeam article is exactly what I'm looking for - any more like
that?  The everyman.org website seems a bit too Dr. Phil-ish for an
essay...:-)
Also, interesting that you posted the Messner links: I just wrote an
essay for this class citing research by him entitled "Is the NFL the
cure for a man's fear of intimacy?"  (The conclusion was an emphatic
"no".)  I think I'd like to steer clear of sports for this essay, just
for a change of scenery.

You don't have to go much farther than hiring policies in the US. The
previous corporation I worked with put red stickers on all employment
applications filled out by females and minorities, and put them on the
top of the stack for HR. Furthermore, they got tax credits for
outsourcing work to female and minority owned businesses. I remember
running the reports on this when I worked in the computer room.

A couple of other ideas to research:

1) Call the local health clubs in your area and ask how many have
clubs for women only. They will gleefully tell you where to find them.
Then ask them how many locations they offer for men only.

2) Check your local area for Women's health clinics. If it's like my
area, you will find clinics that service only female patients. These
are not clinics dealing with "women's" issues. (We should exclude
clinics that deal with issues only related to males or females here.)
You can find small medical offices, usually run by one or two GPs that
simply choose to service females only and exclude any interaction with
males. They generally incorporate with a name such as "Women's Health
Clinic," which gives the impression that they deal specifically with
"female issues," but it is actually a means of ensuring that males
pass on to the next name in the phone book. (By the way, I work in the
medical field, so I see this around town.)

3) Check the papers in a nearby metropolitan area for workshops and
trade shows. You will find Women's business expos, and similar venues
where only female run businesses are able to participate. On the
non-business side, you will find classes such as "Flyfishing for
Women" or "Handguns for Women" and even offerings that are not related
to "traditionally male" interests.

These are just some avenues for you to explore. I don't have any
empirical statistics or published studies to share. But these examples
may help you to compile some of your own studies or look in additional
areas for more studies.
