In around 2013 when there were stories of Swedish neighborhoods where everybody were muslim african immigrants, who followed their own muslim laws and did not follow the Swedish laws. They did not consider themselves to be Swedish, and it was like a seperate small country inside of Sweden.
The Swedish did not consider the africans to be Swedish, even though they were legally living inside of Sweden. The africans did not consider themselves to be Swedish either. Everybody involved knew that the muslim africans are not Swedish and do not belong in Sweden.
Tim went to Sweden at this time and did journalism, and found all of this for himself. He went to Malmo Sweden where there were stories of african immigrants having "no go zones" where only their law is enforced and they are acting like a seperate country. Swedish police were not going there. He was warned that it was too dangerous of a situation for anybody to investigate, so he went there and investigated it for himself.
His meaning of "Swedish people are racist." Is actually saying that Swedish people understand that race is a real thing, and that the africans are not Swedish, and the Swedish are not africans. They are two seperate species, and being in the same location does not mean that they are the same. If this understanding is the definition of racism, then every person on this planet should all be "racist." All white, black, asian, and all other races are all required to be "racist" for their own safety and preservation. This is not the insult that you thought it was, but it is simple racial understanding that is necessary for all people, and what Tim witnessed was that the Swedish had more of this basic knowledge than most other countries he had been to.
