 In 2005 , the Polish Football Association , in an attempt to fight racism among Polish football fans , prepared a blacklist of most common racist and fascist symbols to be banned from Polish football stadiums . The catalogue , co @-@ authored by independent anti @-@ fascist organization Never Again ( Nigdy Więcej ) , listed the Mieczyk Chrobrego as one of the extreme right symbols that are often displayed at the Polish stadiums . The catalogue listed other racist and fascist symbols like the Nazi swastika , the Celtic cross , and the Confederate Flag . After a protest by MEP Sylwester Chruszcz of the League of Polish Families , additional consultations were held with historians , academic researchers and other experts and as a result the symbol is still listed in the catalogue of extreme @-@ right symbols banned at Polish football stadiums . It was also banned by UEFA during Euro 2008 and 2012 .
