You're missing the point, this law is not anti-sex work. You can be pro sex work and still be in favour of this law.
Legalising prostitution doesn't make illegal prostitution go away. On the contrary, by normalising prostitution, the demand increases but the legal (voluntary) supply doesn't. This increased demand is then supplied via increased sex trafficking by crime syndicates. This is a huge problem in the Netherlands that they haven't managed to solve in the 25 years prostitution has been legal.
Even for the legally registered prostitutes, the improvements are limited. Financial exploitation and violence remain rampant.
By decriminalising the prostitutes, the Swedes are effectively providing them with legal protection. By criminalising the buyer, they suppress demand, which reduces sex trafficking, and is the best protection for society as a whole.
As a feminist, I'm a staunch advocate of bodily autonomy and have no issue with sex workers. However, what cost should society accept for their right to provide these services? If for every 10 legal prostitutes, 1 additional person is forced into sexual slavery, is that cost worthwhile to you? How about 1 sex slave for every 5 legal prostitutes? How about a 1 to 2 ratio?
According to this source:
the [Netherlands] government struggles to calculate the number of individuals in its regulated sex trade (numbers range from 6,000 to 30,000)
The law has also failed to curb trafficking, with a reported 5,000 to 8,000 victims each year, two thirds of which for purposes of sexual exploitation
So, best case scenario = 30,000 prostitutes vs 3,333 (5000 x 2/3) sex slaves = 1 slave for every 9 registered prostitutes
Worst case scenario = 6,000 prostitutes vs 5,333 sex slaves = 8 slaves for every 9 registered prostitutes
Now some of these people would have been trafficked anyway, but there is a lot of evidence that trafficking has increased substantially since legalising prostitution.
So, where do you draw the line? Personally, I find the societal cost to be unacceptably high to justify legalisation of prostitution.
The one was a picture of a large number of crosses which Trump said was a burial site for 1000s of white farmers, when it was in fact a memorial following the death of 2 farmers. The memorial was intended to represent all farm deaths of all races. Farm deaths are an issue but the victims are of all races - they kill the farmers, their families and the workers.
There was a video of a political leader singing a song that translates to "Kill the Boer" i.e. kill the white Afrikaans farmer. This video is: a) more than a decade old, b) from a rally of a minority opposition party i.e. not the political party of the people Trump was meeting, c) from a political party that has been losing votes in recent elections, led by someone who was expelled from the ruling party, d) is of a historic protest song from the apartheid era i.e. more than 30 years ago.
This video resulted in a court case, where the court concluded that a "reasonably well-informed person" would understand that when a protest song is sung "even by politicians, the words are not meant to be understood literally, nor is the gesture of shooting to be understood as a call to arms or violence."
This video was a big deal at the time but it's not current, not representative of the government's view, and the person depicted in it is increasingly being sidelined in South African politics.
