In her column for the Daily Express, Ms Widdecombe claims the UK is playing into their hands by giving away our religious freedom by confusing respect with subservience.
She has cited a case in Accrington, Lancashire where a cross was removed from a crematorium in case it caused offence.
"Imagine the uproar if a Christian were to ask for the removal of a religious symbol belonging to another faith?"
When news of the decision emerged in September Councillor Ken Moss, who oversees Hyndburn cemeteries, said: "At Accrington, approximately forty per cent of families state they have no religion and humanist services are very common now."
Following widespread condemnation of the stance it then emerged that a cross would be present in the crematorium, unless families asked for its removal.
But Ms Widdecombe believes the initial decision is one example of people treading too carefully.
"Now, in an even dottier pronouncement, a professor of faith and public policy at Goldsmiths, University of London, says that we shouldn't heat up sausage rolls in the office microwave in case we offend the religious sensibilities of others."
The former Minister of State for Prisons, and MP for Maidstone and The Weald, added: "It is time to fight back and to fight hard.
"The citizens of Accrington made their views heard sufficiently strongly for the cross to be reinstated. Others should follow their example.
"This is a Christian country. It has an established church and Christianity is still the religion of the majority."
