Why don’t we use insults like this anymore?

As Horace said to his friend Mike in Death at the President's Lodging
(much as my friends and I throw insults at each other without meaning
--or taking--offense):

"And you are a nasty, unwholesome, misshapen,
degenerate and altogether lousy scion of outworn
privilege.  And the increasing unpleasantness of your
personal habits, your thick and incoherent utterances,
and above all your embarrassing and indeed painful
inability to talk sense have long convinced David and
myself --though we have striven to conceal it--that
you are already undermined beyond human aid by the
effects of retributive disease.  And your
tailor--whose taste perpetually astonishes me, let me
add--would be grateful for any blood-money you might
raise on [solving the book's mystery]:  it would help
feed the eight children your bad debts are depriving of
sustenance."

It seems these days that most people use cuss words (or whatever
they can do without having to put any thought into to it) in
order to insult someone.
