Social Democrat politician Nalin Pekgul went on the attack against Mehmet Kaplan from the Green Party (Miljöpartiet) in a debate article in one of Sweden's leading broadsheets.
Her piece in the Dagens Industri newspaper was prompted by a statement Kaplan made to the Turkish media, in which he claimed that the reason young Muslims are joining the terror group Isis is because of widespread Islamophobia in Europe.
Kaplan, who is Sweden's new Housing Minister, argued that the government should give more money to Europe's mosques in an effort to tackle the recruitment.
But Pekgul suggested that young people were signing up because they felt lost or rootless and that Islamist extremists were taking advantage of their vulnerability.

"It's unforgivably naive to think that giving money to these kinds of [Muslim] organizations and mosques will work against segregation and will reach out to these youths who are being radicalized," she wrote.
"It's exactly this kind of naivety that people like Mehmet Kaplan are counting on, and it's time for everyone who wants to oppose the radicalization to realize the damage Mehmet Kaplan and others like him can accomplish."
Kaplan previously hit the headlines after he compared Swedish jihadists in Syria to Swedish freedom fighters in Finland during World War Two.
He later apologized and said his comments had been misinterpreted.
But in today's article, Social Democrat politician Nalin Pekgul wrote:
"I'm convinced that he said exactly what he meant to say".
Kaplan, a 43-year-old born in Turkey, is a former spokesperson for the Muslim Council of Sweden. He has been a member of the Green Party since 2003.
"For fear of being labelled as an Islamophobe, no one dares question Mehmet Kaplan and his hidden agenda," added Pekgul.
She also drew comparisons between Kaplan and Jimmie Åkesson, the leader of the nationalist Sweden Democrat party.
"Jimmie Åkesson has claimed time and time again that he isn't racist and that he actually doesn't have anything against immigrants, rather that he just wants to reduce the volume of immigrants.
Similarly, Mehmet Kaplan says that he supports equality between the genders, but there are few secular muslims who'd believe that he wasn't an Islamist."
The word Islamist is a controversial one and some media outlets have been criticized for using it as a synonym for Islamic fighters or extremists.
The term broadly refers to those who want a country's government and society to operate in accordance with Islamic laws, which do not promote egalitarianism.
It is unclear how Nalin Pekgul intended her phrasing to be interpreted.
In her article, she also wrote that with Kaplan in government, Sweden's Green Party heads Gustav Fridolin and Åsa Romson "have sent a clear signal to Sweden's muslims that the Islamists now have the support of the Swedish establishment".
