I have to admit, that you could be right about the reason for the return of the bust. That article is powerful stuff. It would be funny to post a link to that article on a British web site, in defense of Geert Wilder and his film. Ask the Brits, what has changed?
It’s probably a combination of Churchill’s anti-socialism and anti-Islam. No wonder Ozero hates Churchill to the point where he would embarrass the Brits by returning the bust unasked. It’s like showing sunlight and garlic to a vampire.
