The society of Othello is male-dominated, to say the least. In structure and language, the male characters drive the action, while the female characters passively wait. The male reputation is vaunted, while the female reputation is sullied. Males repeatedly and openly use discriminatory language not only against women in general, but against their wives. Iago calls his wife a "villainous whore." Othello calls Desdemona "whore" even more. Other names afforded to women include: "foul," "villainous," and "false."
"Whore" is used 13 times:
be sure thou prove my love a whore,
Be sure of it;
This is a subtle whore,
A closet lock and key of villainous secrets
I took you for that cunning whore of Venice
That married with Othello.
Synonymous with "whore" and no less damaging are words that describe how talkative and unquiet women are. Desdemona says this of Othello:
I'll watch him tame and talk him out of patience;
AND to Othello:
I have been talking with a suitor here,
I pray, talk me of Cassio.
That she reserves it evermore about her
To kiss and talk to.
Iago says of his own wife:
Sir, would she give you so much of her lips
As of her tongue she oft bestows on me,
You'll have enough.
As counterpoint, the word "honest" appears over fifty times in the play, usually said by or describing a male. Observe:
A man he is of honest and trust:
That thinks men honest that but seem to be so,
Iago is repeatedly called "honest" by Othello, Cassio, and himself: "Honest Iago," and "As honest as I am."
So, it is clear: for women to talk is to be loose not only with the tongue, but in bed. Men see women who talk a lot as "whores." If Desdemona is talking with Cassio, she might as well be sleeping with him. And the classic double-standard: men can talk against women openly, but married women cannot talk to men at all, either privately or publicly.
Women are in an unwinnable situation in Othello. Desdemona doesn't talk. She doesn't defend herself in the bedroom, and she is strangled. Emilia talks. She exposes her husband in Act V, and she is stabbed. It's a morbid double standard. If women talk, they are victimized. If women don't talk they are victimized.
To say men use discriminatory language is an understatement.
