, 2018 This chapter discusses Western converts to Islam. Particularly since the turn of the century, when so much focus on Islam has been in the context of violence and terrorism, the embracing of Islam by Westerners has become a perplexing phenomenon. On the one hand, segments of Western society express disapproval of converts to Islam, but on the other hand,
