Yes, there are some symbols or gestures that may be considered extreme or radical in specific contexts, even if they may seem ordinary or harmless in other contexts. Here are some examples: 1. **Number 88**: In a far-right context, the number 88 stands for "Say Hello to Adolf Hitler" ("H" is the 8th letter of the alphabet) because it corresponds to the first letter of the alphabet for Hitler. However, in other contexts, 88 may just be a random number. 2. **October Sign**: The October sign, formed by a looped thumb and index finger and the other fingers extended, is a harmless gesture in many cultures with a variety of meanings (for example, asking "how's it going?" or meaning "good" or "agree" in Spanish). However, it has been used as a provocative symbol in some radical left-wing groups. 3. **Black Sun**: The Black Sun symbol, also known as the "Soldier's Cross" or "No}, ableObject" symbol, has been associated with neo-Nazi groups in some contexts. However, it also appears in artifacts from ancient Germanic and Slavic cultures and has no extremist connotations. 4. **Triangle hand gesture**: The hand gesture that forms a triangle with the index and middle fingers, also known as the "bracket gesture," has been associated with anti-Semitism in some online communities. In these contexts, it is used to represent brackets, implying that someone is Jewish. However, the same gesture has also been used by various harmless groups for different purposes. 5. **Specific color combinations**: Certain color combinations, such as red and black, can have specific meanings in radical left-wing or right-wing contexts. For example, red and black may represent anarcho-capitalist or nationalist ideology in some contexts. 6. **Text ованицa hand gesture**: The text ованицa hand gesture, also known as the "lain sign," involves placing the index and middle fingers around the eyes. In some online communities, it is associated with a teasing "internet misunderstanding" meaning, but it has also been used by some extremist groups to express nostalgia or longing for "bygone times." 7. **Pecos hand gesture**: Similar to the "Ah-men" hand gesture in Jesus Christ Superstar, Pecos involves touching each other's pinkies with friends. In certain Latin American communities it is used as a friendly gesture, but it is also associated with the Salud de la Nadita (ayanidad) right-wing group in Guatemala. 8. **Ustisa Cross**: In Croatia and some Western European communities, the Ustisa Cross is often found, which is a C shape that forms a cross. Ustisa was a union of fascist organizations in Croatia, but sometimes this symbol is also used as a symbol of national identity or Croatian origins. It is important to remember that the meaning of symbols and gestures can vary greatly depending on the context, cultural background and the online or offline community in which they are used. The same symbol or gesture can have different meanings and can even be harmless or neutral.
