Mr. McNamee, in your book you say that:
Whether by design or by accident, platforms empower extreme views in a variety of ways. The ease with which like-minded extremists can find one another creates the illusion of legitimacy. Protected from real-world stigma, communication among extreme voices over internet platforms generally evolves to more dangerous language.
Do you agree that, by providing a place for extremist content to thrive and for like-minded people with extreme views to gather, the tech companies bear some responsibility for grave attacks such as the Christchurch shooting?
