Oxford University’s political-correctness enforcers just learned a painful lesson: There’s always someone ready to point the finger at you — no matter how guilty you feel.

The prestigious school’s Equality and Diversity Unit recently won ridicule for warning students that “not speaking directly to people” — i.e., avoiding eye contact — is a telltale sign of “everyday racism.”

Such a “micro-aggression” might “appear trivial,” the PC police declared, but repeated violations “can be tiring and aggravating,” leading to “mental ill-health.”

No one bothered to explain what’s racist about avoiding eye contact — or how to tell a shy or anxious student from a racist.

But Oxford stuck to its guns — until it was hit with accusations of a “micro-aggression” all its own.

As numerous tweeters pointed out, some people with autism struggle to make eye contact. And making accusations of racism against those with disabilities is itself “insensitive” and “offensive.”

That got action. The mortified dons were quick to confess their sins, apologize for not dealing “adequately and sensibly with the issue” and profess their ongoing commitment to those with disabilities, including autism.

Oxford had also cautioned its students against making jokes that might “call attention to someone’s difference” and so suggest “they do not belong.”

In fact, PC goons like Oxford’s Equality and Diversity Unit offend anyone with common sense. They do not belong in the business of education. And that’s no joke.
