Fathers 4 Justice (F4J) is a father's rights organization founded in the UK in 2002. They are famous for silly and sometimes annoying and/or pushy protests and demonstrations. They have gained some minor momentum as a political force, but have a bit of a media issue in that 1) they tend to be the ones in silly costumes throwing flour bombs, and 2) it is not uncommon for fathers to be denied access to their children for valid reasons. The founder, Matt O'Connor, for example, was originally spurred to action after being granted only limited visitation rights with his kids due to his anger issues, a drinking problem, and mental health problems.
