Can there be a prejudice-free language

Other than blatant or coarse, uncouth language, can there be developed a more subtle language style that would not lead to interpretations of being favoritist, or prejudice?

Communication can be done without coarse language. But can there be an escape from subtle wording that show favoritism in messages? It may ease some social unease if there is. If some will express, without coarse language and favoring hints but still produce an effective message, it might pass the test of some sensitivities of skilled communicators and recipients.

Not only the curtailing of overuse of gender pronouns would ease receptivity but also communiques that don't allow the identity of one member in the message to seem to be preferred over another, or the opportunities may seem or are prearranged to favor one over another, at least it might be perceived so, if there is a message put out that is supposed to be received as unbiased or neutral. Some messages do appear that way as expressing bias even though the author did not intend for it to come across like that.

Language expression can be relative, like Venn diagrams. What may be intended as inclusionary wording could be exclusionary if there are elements that are outside the inclusionary circle and remain so, even if one uses the wording "all" or equivalents. "All", for example or "every body" etc., may only include to what purpose constitutes its use.

To make an expression totally inclusive, one may have to resort to phrasing such as, "every single one" or "each and every single one".  Interpretation of "all" and other similar expressions may produce an assumption that marginalizing is allowed on those perceived not to comply or fit the criteria of the topic.

Caution should also be used if there messaging that may overpraise an occasion or person which may lower expectation(s) of another, or underpraise other's contribution can be subject to interpretation. Mutual regard will better relational coordination and cooperation.

One should consider that the background of experience oneself assumes to communicate from will not be the same as the recipient. Assumptions may be read in while the author may not have full knowledge of the background of the intended recipient because it is assumed by the author that other's experience and background are the same. The short coming is the message will appear to be favoring the background of the author rather than others, even if unintended.
