Social media, for better or for worse, has become the primary means by which we share information, by which we negotiate our values and by which we negotiate even the corpus of information that we call facts. It has become the main means by which we set our norms of attitude and behaviour. As such, it has a resocializing effect on the off-line world such that with the heightened prevalence of hate and the lies that always underpin hate—lies and hate are inextricably interlinked—what we see is a growing normalization of hateful ideas and hate speech itself.
To address the second part of your question, I think the real issue that we have with the growing prevalence of hate is that it's fed to the people who are victims, and they engage with it. It therefore makes the world seem more hateful and it leads to polarization as a result. It's also fed to the people who have shown some interest in it before, but the truth is that it's also fed to just normal members of the public and therefore has that resocializing effect as well.
Through all three elements, whether it is terrorizing Muslims, encouraging people who hate Muslims or making the general public feel that most people hate Muslims, it has [Technical difficulty—Editor] but nevertheless highly pernicious effects.
