Word for Gentleman Not Speaking Badly of a Lady

Forbearance?

Decorum?

Tryagain and Roger-

Thank you but not the word I am looking for.

The word I am looking for, comes up if a man says something perhaps to take blame away from himself by saying something compromising about a lady.

After he says it people may turn to him and say that's not [the word].

I think that the word begins with the letter R.

It came to mind today when I read of a congressman charged with stealing from his campaign fund. His response was to blame his wife!

Not [R-word].

Gallant

Looks like the R word you wanted was Republican.

Have you considered posting crossword puzzle questions?

Be like Gallant!

Sexism?

I have heard "he was quite the gentleman" or "very reserved", "very refined, reputable or gallant

That's about all I can drum up right now

Reprehensible?

Mansplaining.

That's not cricket.

Thanks for everyone's help. I have the answer: gallant.

I just double checked... Gallant generally means fashionable, as in finely dressed. I think you can be gallant while you are speaking badly of a "lady" (although any aspersions you cast upon her character should uphold the standards of good grammar and diction)
