It's come to this

Students at King’s College in London no-platformed Boris Johnson, the mayor of London, after he criticized Obama’s decision to remove a bust of former Prime Minister Winston Churchill from the White House. Johnson had been scheduled to participate in a debate on the merits of the European Union, according to The Telegraph.

Johnson accused Obama of having an “ancestral dislike of the British Empire” because of his Kenyan heritage. The event’s organizers deemed Johnson’s remarks unacceptable.

“Given your inappropriate comments and inferences towards President Obama’s Kenyan heritage, of which he is rightly proud, and your general tone of disrespect over the past few days in relation to the President of the United States of America, we are now formally withdrawing your invitation at Kings College London,” wrote the students.
