Wrestling is not popular in Russia as a whole.
Wrestling is popular in a few republics, mostly in the Caucasus region and Siberia. Wrestling in Russia is practiced by almost no ethnic Russians, but instead by minority ethnic groups, some of whom don't identify as Russian at all.
Russians are bad in wreslting (if we dont talk about Yarygin and Karelin), they love ice hockey, drink alcohol and say **** about America but love Trump. Caucasus people (Dagestani, Chechens etc) love sport (combat sports) and Mongolian people who live in Sibiria (Tuva etc)
