I was talking about the sentence that I quoted.

The sentence you quoted basically says that crime rates are not the reason for the rise of right wing parties. Nothing about fearmongering, that was my point.

However, my opinion is that the AfD and other parties wouldn’t be successful if the established parties had acknowledged the outliers.

And how do you think those outliers should have been acknowledged? Outliers are a regular occurence in statistics. Any acknowledgment that goes beyond “Yeah, that’s strange, however this is just an outlier at the moment, nothing to worry about yet” at the first sight of such an outlier is an overreaction. The far right overreacts (and I accuse them of doing so knowingly) by erecting bogeymen and accusing others of not acknowledging a statistic outlier by not overreacting. Combine that with conservative and neoliberal politics that did not appropriately react to actual crises, continue to exacerbate the living conditions for working class citizens, amplify precarious situations and play the same bogeymen as the far right and you have a nice boost in popularity for the far right. A media landscape that on one hand supports far right narratives and on the other hand fails to contextualize news and politicians’ outputs also helps a lot.
