Swearing

In olden days, the strongest swears available pertained
To taking Yahweh’s name in vain, but then religion waned.
As people got more privacy, they felt a lot more shame
For designated private parts and functions of the same,
Which thus became the basis of a second kind of curse.
Today, the most offensive words are demographic slurs.
Perhaps there’ll be a fourth wave, but it’s hard to think of how
The people of the future will take more offense than now.
