Russian ski jumper Irina Avvakumova has participated in events aimed at justifying Russia's military aggression against Ukraine. Avvakumova, who has won multiple world championships and Olympic medals, has been seen wearing a letter "Z" on her uniform during rally.

Many people have criticized Avvakumova's actions as promoting aggression and disrespecting the sovereignty of Ukraine. Her actions also raise concerns about the role of sports in promoting political messages. 

While athletes have the right to express their opinions and beliefs, using sports to promote political agendas can create tension and division.
