I got the same impression when I went to some parts of Western Europe; I thought these places were only inhabited out of vanity and habit. The people there live for nothing. It's an entirely small and small-souled kind of person who lives there, something that has been bred I believe by centuries of Christianity, quite deliberately, which culminates in the final intention of this doctrine, the modern form of democracy and liberalism and in particular the modern European. Therefore saying that Europe is abandoning Christianity and through this is abandoning its identity is a perversity, but an enjoyable one.
The guy in the video, which I only just watched, is plagiarizing Michel Houellebecq from his book
The Map and the Territory.
I recommend this book, very enjoyable; the end presents a future version of France that has become merely a tourist destination for Russian and Chinese tourists, providing them a very "authentic" experience of French life and cuisine. The rest of the book is about the career of an artist, and very enjoyable.
