I sort of think that it might maybe have a bit of a point somewhere, but I think the central themes of this article are way too hyperbolic and she seems to have no proper measure of the coverage and is mostly running through what is supposed to be received wisdom in progressive circles, it seems to be reacting rhetorically rather than trying to take . This bit sort of irked me even though I'm not whte.

But in cultures with a strong legacy of white supremacy, only white men are considered to have domain over white women. This, in part, was what shielded the women attacked in Cologne from probing questions about their alcohol consumption, clothing choices, and general “respectability”: their Middle Eastern and North African migrant assailants weren’t seen as having a natural-born right to sexual access to their bodies.

I am dealing in the same kind of 'received wisdom' as her but iirc sexual assaults and general crime, especially against people who are perceived to be vulnerable are a big feature in negative ingroup/outgroup relationships between groups all over the world, two examples I can think of are Muslim/Christian tensions erupting into violence in Egypt following the alleged kidnapping of a girl who wanted to convert, (South) Asian vs Caribbean community tensions erupting into violence on the streets after rumours being spread around of the sexual assault of a Caribbean girl by Asian men, etc, etc. This is not 'white supremacy' this is some extremely common theme of human relationships with examples too numerous to mention. The other bit seems like somewhat empty rhetoric that only works on people who agree with you also.

This bit was also somewhat disingenuous

Though the Cologne attacks were undeniably exceptional in terms of number, nothing about the nature of the crimes was alien to contemporary Europe. There was no offense committed by migrant men in Cologne that hasn’t also been committed by white European men on countless occasions...

I think this is obscuring that it is worth considering if there might be a problem with cultural attitudes of some people from some parts of the developing world, and if those are generally different to those of people from the host country. It is obvious imo that chauvinism/racism/ingroup-outgroup dynamics and unpleasant attitudes of 'purity' played a large role in the abuse and grooming of kids (of both sexes) by men (and women) who were almost all Muslim and disproportionately from some small part of Pakistan, are similar things going on with assaults connected to the refugee crisis and were these 'tararoush' group harassment. I think that if the author wanted to seriously deal with this question they might look at the rates of perpetration of this type of crime for different ethnic groups, cultural attitudes and what actually went on. The way it's written seems slightly obfuscatory imo because these are actually serious questions that people might want to consider.
