To be a gentleman

Although I was taught by my parents to be a gentleman, by the time I reached adolescence the leading cultural indicators appeared to regard the entire notion as sexist or patriarchal. Yet Judi Vankevich, aka The Manners Lady, disagrees: “Gentlemen”: An Endangered Species? She has put forward ten principles for raising a gentleman. Some might argue that discarding such quaint practices as holding a door open for a lady has exacerbated such ills as date rape and violence against women. Others would likely hold that it has led to greater equality between men and women. Are these sorts of courtesies obsolete or do they make for better relations between the sexes as well as between young and old?
