Gallantry (noun): dashing courage; heroic bravery; noble-minded behavior

From A Jury Of Her Peers: “And yet,” said he, with the gallantry of a young politician, “for all their worries, what would we do without the ladies?”

A young politician back then were probably seen as with power and respect, nowadays, there are seen also like that but one would think that they are just corrupting our system to fit their needs. So now, I understand that the way he talked, had some emphasis due to him being a politician.
