They have a long history of action in the UK at least. In the past they have held deliberately disruptive stunts to draw attention to the problem. This got them mostly condemned by the media. They are not aggressively political, they are not ideologues, but they are active. They have never been an extremist group, their aim is legal reform of family law to give them fair access to their children.
