The outburst came after Walker claimed the UK was “addicted” to welcoming people “who don’t want to integrate”.
He said: “We’re addicted to unskilled labour, we’re addicted to people who don’t want to integrate, we’re addicted to people who don’t want to speak English and we should just stop it – it’s crazy.”
Reacting to the commentator’s rant, Bidisha said she was “not interested in arguing back and forth” or “sloganeering”.
She continued: “What we need to do is look at the numbers. We actually have relatively low levels of migration and immigration – if you look at our refugee numbers, we have extremely low levels.
Either teach them to speak English or don’t let them in in the first place
“Because someone who comes over and works for a very low wage is still having to pay the same prices for things.”
A raging Walker attempted to interrupt before being accused of being “sexist”.
Bidisha blasted: “Please don’t interrupt me, it’s not polite, it’s incredibly sexist to interrupt women.”
Fighting back, the New York Observer columnist insisted he was trying to make a point.

Speaking on the news channel, Walker said migrants were “ruining communities just by their sheer numbers”.
He added: “Either teach them to speak English or don’t let them in in the first place, I would personally go for the second argument.”
The fiery clash comes after a cross-party parliamentary group called for newcomers to be expected to study the language before coming to the UK or to be enrolled in compulsory classes on arrival.
Labour MP Chuka Umunna, chair of the All Parliamentary Group on Social Integration, said: “It’s clear that immigration has impacted on different communities in different ways and the pace of change has alarmed many.
“The Government has a duty to address the lack of integration of immigrants if it is to address this.”
