Sweden is one of the most feminist countries, makes sense that ugly guys are treated like shit there
I didn't watch the video, but in the comments there wasn't any good comments about why. Same here.
The reason why Sweden is at the moment the absolute worst country for incels is pure mathematics; massive immigration to population ratio; immigrants are overwhelmingly young and male. Small population, big immigration. Sweden has liberated completely work-based immigration, the only country in Europe to do so. They have more fake refugees per capita than any other. (real refugees in Lebanon, Turkey, Jordan don't affect the sex ratio, but the refugees that get to Europe are overwhelmingly young males). They have massive numbers of so called "paperless" that do not show in statistics.
This is a US and UK -centric website, that's why the discussion here is very different than in some European countries. In Sweden what the local young men hate the most? The immigrant young and handsome men taking their women! This is a VERY usual scene in the streets. But one never sees a local man with a Syrian or Afghan woman. Muslims are encouraged to take local women, but muslims and islam bar their women from dating and marrying local men. If that sometimes happens, they "honourkill" their daughters.
Sweden has far more 16 and 17-year-old boys than girls - the imbalance is down to the number of migrants arriving in the country.

The flow has been big and ongoing still after 2015. Most do not get positive, but stay regardless. Only tiny percentage is actually successfully deported.
You can see these dynamics very clearly in voting behaviour. Young men vote anti-immigration, women prefer uncontrolled male-dominated immigration, because it benefits them greatly even if they don't themselves date an immigrant man, they can afford better local men, and the bottom men are left being surplus. The immigrants are usually very fit and handsome elites of their countries. They had lots of money to pay to the smugglers.
