[9] In October 2016, Dekker appeared in the four-episode EO television show Rot op met je milieu ("Get Lost With Your Environment"), in which she took up the position of environmental activist.

[13] On 4 December, during VegFest 2016, Dekker lectured about her experiences during Rot op met je milieu, and about veganism and activism in general.

[15] On 20 January 2017, Dekker was part of the Women's March demonstration by several hundreds of people against American president Donald Trump (inaugurated that day), and against Geert Wilders, at the Museumplein in Amsterdam, "because they claim to serve the common man, but they don't actually do so," and were using Mexicans, Muslims and refugees as scapegoats.

[20][21][22][23] The weblog she maintained these days was widely read, and received many negative reactions from Dutch right-wing media such as PowNed, who published a scathing piece entitled "All of Holland Hates Anne Fleur Dekker".

[7] On 16 March 2017, one day after the Dutch general election of 2017, during which Thierry Baudet's party Forum for Democracy (FvD) won two seats, Dekker wrote an opinion piece at Joop.nl, which was read about 70,000 times.

[26][27] Next, on 18 March, the right-wing populist conspiracist website liefdevoorholland.com resurfaced a few earlier online posts of Dekker as well, including an old tweet stemming from 19 July 2016.

[28] At the time, Dekker responded to a Belgian woman who had proposed on Facebook to throw stones at a mosque with "at least 500 people, as a 'fun action' in response to the radical Muslim violence of the past few nights".

[6] The website made a collage of an edited photo of Dekker with devil horns and two of her tweets, added an accusation of electoral fraud to the post and demanded a recount.

According to the NOS, Hilversum mayor Broertjes had refused this because she had a "distinct political profile",[4] but Dekker herself claimed she had already indicated two weeks before the elections that she would be too busy.

[6] Allegedly, this was a lot worse because she was a woman, and according to her "all the right-wing platforms are now running rampant: GeenStijl, De Dagelijkse Standaard, The Post Online".

Former VVD politician Ed Nijpels criticised her behaviour as "duplicitous", whereas PvdD leader Marianne Thieme defended her right to free speech.

[2] The next day, controversial Het Parool columnist Theodor Holman wrote that Dekker's radical activism turned him on, and he wanted to have sex with her.

[33] Dekker reacted furiously that he was a "filthy creep", that she felt "verbally assaulted", and called on the newspaper to prevent him from publishing such "misogynist locker room columns" in the future.
