Celtic have taken measures to reduce sectarianism. In 1996, the club launched its ''Bhoys Against Bigotry'' campaign, later followed by ''Youth Against Bigotry'' to "educate the young on having ... respect for all aspects of the community&nbsp;– all races, all colours, all creeds".<ref>{{cite news |url=http://news.bbc.co.uk/1/hi/scotland/1593970.stm |title=Bigotry puzzle for Old Firm |work=BBC News |date=11 October 2001 |access-date=6 April 2006 |archive-date=13 March 2007 |archive-url=https://web.archive.org/web/20070313041441/http://news.bbc.co.uk/1/hi/scotland/1593970.stm |url-status=live }}</ref>
