In September 2011, a school girl wanted to support the country's Blue Friday, a nationwide campaign to raise awareness of prostate cancer. She was banned from supporting it because students were only allowed to support female causes, even though the girl's own grandfather had died from this cancer. This raised issues in the newspapers[2]
