Maybe you have spotted them: adverts in bus- and tram stops for Gendertwijfel, a transphobic organisation that wants to overthrow the new law that should make it easier for transgender people to change their gender with the government.
To prevent people from seeing such transphobic propaganda, the website Gendertwijfels was launched. Deliberately with a very similar name to lure people to the website who simply enter the URL wrong. The website contains information for those who are in the process of discovering their own gender identity. Great initiative!
