Your house is burning down, right when you are writing to thank your aunt for knitting you an unattractive holiday sweater. But the fire can wait until you have finished your unexpurgated multipage letter so you can get it in tomorrow’s post, right?
Multitasking can solve that problem, too.
Seriously, in the USG, we have what amounts to organized crime mafias, domestic and foreign, who have infiltrated and are actively involved in tearing our country apart. Eliminating these infections is far more important that pursuing perpetual petty pursuits. In fact, there are only a minimal number of federal criminal justice pursuits more important.
Only when the government is purified of these scoundrels and they are spending many years in federal penitentiaries do we have *any* latitude to engage in business as usual.
None of your examples is equivalent to pornography, because people don’t often die from writing letters or knitting sweaters.
