See, that's what I mean. The Right, especially the Alt-Right on Youtube, has been pointing to the Cologne New Year rapes as proof that letting in Muslims has resulted in mass rape. But this happened back in 2015. Five years later, there hasn't been another case like this. Another case that keeps coming up is one where a Muslim migrant raped a young boy at a public pool in Vienna. But this also happened in 2015. The reason the Alt-Right hasn't been able to use newer examples is because it's just really rare that they happen.
There has been cancelled music festivals in Sweden, but that's not because there's a rape problem in Sweden, it's because people believe there is.
