This is quite literally what they said: "They will also be forced to leave, even if they are born in Sweden, because they have no natural connection to Sweden. They are not Swedish."
They want to deport anyone that isn't Swedish enough, even if they're native-born Swedes.
"They" in this context seems to be, Somalian living on the social welfare state. Not "every non-white person".
> Why won't the Liberals push for deporting 100 000 social welfare-Somalis?
So, it sounds like people who showed up and are leaching off the state without giving anything back. This will put a strain on these systems for the people it was actually designed to support.
