Watch this news anchor correct Mustafa Kamal's casual sexism on live TV

Last night's regular late-night news programming was interrupted by a welcome spot of gender sensitivity 101.

It went like this:

On the current affairs talk show Aaj Shahzeb Khanzada Ke Saath on Geo News yesterday, host Shahzeb Khanzada was talking to the Pak Sarzameen Party (PSP) Chairman Mustafa Kamal about his rift with Muttahida Qaumi Movement-Pakistan (MQM-P) leader Farooq Sattar.

During their conversation, Kamal described Sattar's recent behaviour as "auraton kee tara rona dhona, chooriyan torna, cheel ki tarah chillana" (i.e. crying like a woman, smashing bangles, shrieking like an eagle).

We've heard worse references to women on national television go by with little consequence, but Khanzada, refreshingly, cut in to correct this instance of casual sexism.

"Apologies for the intervention, but it's not right to refer to women like that," Khanzada said. "Women are a powerful group. It's not right to refer to them like this. That's all, please continue."

Khanzada clearly took Kamal by surprise, as he took a small pause to perhaps, gather his thoughts.

But far from apologising for his mistake, Kamal tried to defend it: "Thank you for correcting me. I agree with you. But with reference to what I was saying, you may know some strong women, I know some weak ones..."

"Men can also be weak," Khanzada replies with a laugh. "Anyway, we can continue our discussion."

Khanzada's 10-second intervention is an example to all men in the public eye: it's not that hard to call out sexist behaviour.

A well-timed comment can make all the difference and make an offender rethink their actions.

Twitter, of course, has erupted in cheers since the news clip of this exchange has gone viral:
