Whilst I didn't make this claim because I'm not sure the terminology is correct, I did happen to notice that one of the points raised during the millionwomenrise march was that "One woman in four will experience sexual assault as an adult."
So let's assume that women in Sweden are assaulted at the same rate as they are in the UK.
Apparently in Sweden, "individuals with an immigrant background made up 61% of all rape convictions between 1985 and 1989" (wp)
I think it's fair to suggest that that figure has either remained or more likely increased, given the massive rise in immigration since thenand the reports of ongoing attacks throughout Europe.
Now getting an exact figure on this is being made deliberately difficult simply because Swedish politicians/police cynically refuse to register ethnic or immigration background while compiling rape statistics, and have in the past pretended that raping Somalians were really native Swedes.
To have a corrupting statistical bias at Government level would suggest to many that they are hiding something.
But just going on what we can reasonably assume, we can suggest that 1 in 4 Swedish women are going to be assaulted and that the majority of those attacks will have been committed by immigrants to Sweden.
Not quite the headline, but near enough for this to be a legitimate social concern.
To argue against such a reasonable position suggests that some people are more concerned with how this looks than the safety of women.
This unprincipled blind spot amongst the Left is an interesting contradiction, and one they haven't properly explained yet.
