V. Vladimirov decided to take a bold step - because these days, any attempt to objectively study Judaism and Jewishness inevitably leads to accusations of “anti-Semitism.” This topic is something like a litmus test by which one can judge whether a person is capable of thinking independently or not. The unbiased researcher is struck by the number of negative comments about Jews throughout literally the entire history of mankind. What is the reason for this? Are there objective grounds for such an attitude? By the beginning of the 21st century, a wary attitude had developed towards Islam and its adherents. It is Islam that determines certain behavioral characteristics that are characteristic of Muslims and uncomfortable for other cultures. Due to its geographical location, our country inevitably comes into contact with the Islamic world. Does the spread of Islam pose a threat to Russia? The author tried to answer these questions in his new book.
