Symbols and Imagery
Many mainstream groups use imagery as a way for fellow supporters to recognise each other, from the National Trust oak leaf, through to music band logos and sports team shirts. This use of imagery is also used by supporters of different ideologies. However, while some far right or far left supporters have tattoos or wear recognisable symbols on their clothing in order to intimidate or openly proclaim affiliations, others want to continue operating in mainstream society, undetected by those not in the know.
Some group members or supporters now use symbols that are deliberately chosen to look innocuous and blend in. Whilst some of the symbols they use are adaptations of existing racist images; some have been adopted from benign cultures and used for the purpose of recognition between like-minded individuals. Therefore, please be aware that not everyone sporting these adopted symbols on tattoos or clothing is an extremist - some may have worn them because of their original meaning, or may just have a symbol that is similar to the adapted versions, but different.
The following links provide information on the range of symbols currently being used by Extreme right and Extreme left supporters.
