You are aware that disciplines exist, right? And that within those disciplines, words often are used as technical terms, with meanings that do not exactly map on to colloquial usage? For example, when physicists talk about 'energy', they are not talking about a state of mind that people can have (eg "I'm really full of energy today"). That doesn't mean that physics is wrong or orwellian, it just means that you need to get an education before making pronouncements about it. In the case of "sexism", when we are talking about it here we are usually talking about it from within the disciplines that actually deal with it (either sociology, gender studies, modern history, philosophy or etc). Within all of these fields, sexism is a technical term that means (with slight variations between fields) exactly what steveklabnik above summarised it as.

No, we are not. That is the entire point. We are not in a women's studies department. We are not women's studies majors. We are not talking about women's studies. So the terminology of women's studies is not relevant.

No, it is not. History and philosophy do not use sexism that way. Only a minority of sociologists do. The only example you listed that is actually correct is women's studies.
As I have said elsewhere, the terminology is relevant because it is the terminology of the disciplines that deal with this stuff. I can accept that people will want to talk about this stuff without knowing anything about it at first - that makes sense, and without already knowing that it has already been studied how would they know? When people learn that there is actually a prior literature and well developed disciplines that deal with this stuff however, then deliberately turning their back on even the most basic part of the literature and the discipline when there are people who are literally explaining it in front of them is rank anti-intellectualism worthy only of contempt and scorn.
When looking at issues of gender in history, modern history does use the language of privilege - ie sexism might be talked about as manifest in terms of what records or history is recorded and treated as important by the people who are being studied. When discussing issues of gender, modern Philosophy has to deal with system level analysis - hence the use of ideas of systemic sexual discrimination as sexism. Recent sociologists seem to non-controversially use this terminology also.
