The thing is, Paludan is exploiting a situation for his own political gain....He has been chased out of Denmark, and has chosen Sweden because as a citizen, they cant kick him out.
Sweden has gotten a lot of refugees over the years and has failed in integrating some of them into society. It is a general problem in all of Scandinavia, where underlying racism or xenophobia is a problem. This, like the US and in part the UK, has spread to the police, who target "brown" people as all "brown" people are likely criminals. This leads to high animosity towards the police in migrant communities.
Now you can say.. but why dont they just integrate. Well it is not so simple. Most want to integrate, but when you are refused a job based on your first or last name for the 100th time, then well...
There is a story out of Denmark years ago. Iraqi kid flees with his family to Denmark in the 1970s and he becomes a Danish citizen. He goes to university and becomes an telecom engineer with high grades. He cant get a job in Denmark, despite there being a need for telecom engineers. He then reluctantly moves to Belgium and gets a job in Belgian Telecom and goes up the ranks and becomes part of the leadership. Years later, the former Danish telecom giant buys Belgian Telecom and he is chosen as the guy from Belgian Telecom to work out of the main office in Copenhagen. There he becomes boss for... the guys who refused to hire him a decade earlier in Denmark... irony no? This is a story repeated across the western world.
Poverty, discrimination, lack of opportunity and so on, creates the problem we are seeing in Sweden and other western countries. BLM is a direct consequence of racism, poverty and discrimination. The Tottenham riots in the UK were a direct result of police violence against black men in the UK and so on and so on.
Regardless of why... The Swedish police, in my opinion, are partially to blame for all this violence. They dont HAVE to give Paludan and his nazi followers permission to hold these gatherings and yet they do for some reason.
