This article investigates the impact of intolerance on online political participation among young Europeans. Based on the theoretical insights of (in)tolerance, political participation, youth, and media studies, we explore whether and to what extent intolerant attitudes drive young people’s online political participation. In doing this, we draw on original survey data with booster samples for young people, covering nine European countries. Our results show that intolerance leads to more online political activities among young people. However, these individuals are not socially isolated and marginalised; in fact, the effect of intolerant attitudes on online political engagement is reinforced by participation in offline unconventional forms of participation and social capital. Our findings bear important consequences for the understanding of intolerant attitudes, youth politics, and (online) political participation.

本文调查了不容忍对欧洲年轻人在线政治参与的影响。基于（不）容忍、政治参与、青年和媒体研究的理论见解，我们探讨了不容忍态度是否以及在多大程度上推动了年轻人的在线政治参与。为此，我们利用原始调查数据和针对年轻人的加强样本，涵盖九个欧洲国家。我们的结果表明，不容忍导致年轻人更多的在线政治活动。然而，这些人并没有被社会孤立和边缘化。事实上，线下非常规参与形式和社会资本的参与强化了不容忍态度对在线政治参与的影响。
