Why insult the millions of users relying on Tailwind?

What's the insult? Tailwind is specifically for people who don't like writing CSS because it avoids various ways CSS works and comes with predefined styles.

"Pathology"

it's objectively a pathological use of CSS because it circumvents the C (cascade)

More discussion should be had if the cascade is even beneficial in the first place.

It's ironic because standard software development practices advocate isolation.
