This has to do with showing respect for elders as compared to being rude and crude. Perhaps you could run a google search and do a bit of research on this subject. "“Stand up in the presence of the elderly, and show respect for the aged." (Leviticus 19:32) In the same way we should show respect for our president. Because he is the leader of our country. If we agree with all of his polices or not.
The law provides protection: "If the victim is elderly, in addition to the minimum mandatory sentence imposed by the statute, the statute also reclassifies battery from a misdemeanor to a felony, punishable by a term of prison of up to five years and a fine of up to $5,000."
Young and old, esp very young and very old people are to be given extra respect and consideration. Esp in the case of Hugh Hefner because he was just a playboy. But the fact that he lived to be 91 would tend to show that he did not abuse women they way you would expect from a player. So that would tend to show he had respect and consideration for them.
