Most of his conflicts with Khan, for example, are over issues of lawn care, rather than race,

In modern times, all it would take is a 25 second cell phone clip of hank yelling at Khan over the grass entitled, "Redneck threatens to call police on immigrant" to get him fired from Strickland propane.

Also as memory serves correctly Hank was "block captain". Can you imagine him giving a noise complaint warning to a black family? youtube video would be entitled, "racist white male threatens black family with police for having birthday party"

Ironically, the coward dale, would be much safer in modern times than Hank, because Dale is too much of a coward to try and confront people to do the right thing. Or what they perceive to be the right thing.
