At the heart of "tourismophobia", past and present, is the question of the masses and the differentiation between those who call themselves "travellers", denying their own tourism, and tourists. Tourismophobia studies the persistence of the repulsion for them, and though their number is infinitely greater today, they are no longer socially the same and practices have radically changed. This book brings this cultural invariant out of the shadows to understand the driving forces behind this social posture, which has taken a new turn with climate change. Without overlooking the negative effects of tourism, this book is a response to the current debate on "overtourism", which is the most contemporary form of tourismophobia.
