<p>Against the backdrop of current assumptions about the increasing politicisation and radicalisation of young people, this article examines the socio-political attitudes of sports club members in Germany aged between 13&#xa0;and 26 and the extent to which there are differences between these members, members of other clubs and non-club members, as well as older people. The data is based on a&#xa0;nationally representative population survey conducted in the summer of 2024. They are analysed against the background of common assumptions about sports clubs as political socialisation institutions in which specific values and attitudes are anchored that could lead to the development of shared orientations among club members through regular social interactions and practices. First, differences in the nine (anti)democratic attitudes examined between the age cohorts and between club members and non-members are presented primarily in descriptive form on the basis of mean values. Finally, covariance analyses are used to estimate the main effects of age and club membership as well as interaction effects for the dependent variables, with the influence of relevant third variables preceding club membership being statistically controlled. In the present study, young people do not stand out for having particularly exclusionary misanthropic or right-wing extremist attitudes. Rather, the mean comparisons by age group show that xenophobia, nationalism, relativization of the Nazi era, racism, and antisemitism increase with age. However, it is striking that younger people report lower political self-efficacy. Sports club members show higher agreement scores on most pro-democracy attitude scales than non-club members, and conversely, they show lower agreement scores on most misanthropic attitude scales. This is particularly true for those sports club members who also belong to a&#xa0;second, non-sports club. With regard to political efficacy beliefs and trust in the political system, we find robust differences in favor of (sports) club members. The covariance analyses show rather small effects for age and club membership, with interaction effects not significant in the majority of models. However, the findings also show that, especially among younger sports club members—when the influence of other sociodemographic characteristics is statistically controlled—the approval ratings for xenophobic, nationalistic, and statements relativizing the Nazi era are similarly high or even higher than among members of other clubs or non-club members. This finding indicates that further youth-specific measures against right-wing extremist and misanthropic attitudes in sports clubs are sensible and appropriate.</p>
