“Secularism is not the problem,” he said during a visit to the deprived Paris suburb of Les Mureaux.
Secularism guarantees Muslims and other believers the freedom to practise their faith in peace and remain “fully part of the Republic”, Macron said.
“The problem is an ideology which claims its own laws should be superior to those of the Republic.”
The fault partly lies with France, he added, which stands guilty of fostering the “ghettoisation” of ethnic minorities and the poor that created the conditions for radical Islam to thrive where the state had failed. To tackle its “insidious” spread, he outlined a five-point plan that would be translated into a bill debated in parliament in January.
Measures include making school education compulsory for all children over the age of three in order to avoid “indoctrination” by extremists in madrassas.
Banning home schooling, except on medical grounds, he said the role of teachers was to “train citizens, not believers”.
The 42-year-old confirmed France will phase out the tradition of countries such as Turkey and Algeria sending imams to preach in its mosques.
Macron also announced plans to boost the number of Islamic courses in French universities to avoid “Anglo-Saxon influences over social sciences”.
Speaking just days after an Islamist stabbed two people in Paris outside the former offices of Charlie Hebdo, a magazine, he said: “The country has been hit by Islamic terrorism since 2012 and we have progressively rearmed against this threat.”
Macron, a centrist, also said that France’s colonial past had helped stoke problems and he acknowledged the country’s social housing policy required “deep change”.
“We have created our own separatism in some of our areas. We cannot keep adding poverty to poverty,” he said.
