The columnist was branded “stupid” for her controversial remarks aired during an interview on Fox News on Wednesday night.
Two people died after the attacker drove his vehicle at speed along the pavements of Westminster bridge before killing PC Keith Palmer on the grounds of Parliament.
Ms Hopkins claimed to speak on behalf of the nation as she told Tucker Carlson: “I’m tired of hearing on the media, ’we will not be cowed by terror, we stand united’. But that’s the message in London, that is not the message here in the UK.
“People are cowed, people are afraid and people are not united. Great Britain is more disunited, it’s absolutely divided, more than any time in its past.”

People are cowed, people are afraid and people are not united
She continued: “We are, in fact, a nation of ghettos, I think liberals here think multiculturalism means we all die together and that’s not a view that I support.”
Speaking about multiculturalism, the 42-year-old added: “All that conflict, all that war, all that tension, that didn’t get left behind, they just brought it here.
“If we imagine we’re united, that’s a lie. All those hashtags, lights, candles, making hearts with your hands – that means nothing. Put that stuff away.”
However, the extraordinary remarks prompted an angry response from many social media users, including high-ranking politicians.

Conservative James Cleverly, who had previously served with PC Palmer in the Royal Artillery, berated Ms Hopkins on Twitter.
The MP for Braintree wrote: “I'm on a train heading towards Westminster. No one is cowed, afraid or divided. Please stop your stupid attention seeking comments.”
Another furious user said: “This gargoyle is talking nonsense. I am in London. No one is cowed, we are not afraid and we stand together.”
A third retorted: “This is b*******, we are fine. Katie probably didn't take the tube this morning, unlike the rest of us.”
A fourth said: “Why the hell is she the UK's spokesperson on this? She is wrong. We are united and we are not afraid.”
