The British government has banned Renaud Camus, the 78-year-old philosopher behind the ‘Great Replacement’ theory, which claims Europe’s indigenous populations are being displaced by migrants. The Home Office declared his presence contrary to “the public good,” barring his entry to the UK.

Camus sharply criticized the UK government, accusing it of hypocrisy for targeting him while being lenient on more severe threats. In an interview with The Daily Telegraph, he stated that “of all the European governments guilty” of permitting unchecked migration, “the British government is one of the guiltiest.”

Michael Deacon, who is a columnist for the paper, argued that if criticising mass immigration can result in you being barred from Britain, then free speech is dead. He also asked the important question of what the decision means for British citizens who agree with Camus’ theory:

Does this mean that the presence of these British people is not conducive to the public good, either? If so, what do our authorities propose to do with them? Should those British people be banned from Britain, too?

Sam Bidwell of the Adam Smith Institute also criticised the state for being inconsistent with who it lets into the country, having previously welcomed a Muslim cleric banned from preaching in Pakistan due to extremist rhetoric, as well as Zimbabwean cleric Ismail Menk, who has described homosexuals as “worse than animals.”

Others have drawn notice to the fact that while Camus is no longer allowed to enter the UK, the government continues to do effectively nothing about the arrival, most days, of hundreds—and sometimes more than 1,000—of illegal migrants.

Camus, who was set to speak about immigration at an event later this month, is now planning to appeal the ban.
