Yekaterina Mizulina is the daughter of Russian legislature member and senator Yelena Mizulina.
Yelena Mizulina is the head of the Legislature's Committe for Family, Women and Children. She is known for her traditionalist and anti-male legislation, particularly, against those who pays child support and against male parental rights. She even used the term "male lobby" in a way, analoguous to "pedophile lobby". She accused Wikipedia for being a cover for "pedophile lobby". She was also the main proponent of "juvenile justice", the idea that kids should be taken from parents who do not make efforts to educate them in government ideology.
Yekaterina Mizulina, the daughter, is the head of the League for Safe Internet. She is known for initiatives related to Internet censorship, ban of VPN services that allow to access prohibited sites and writing compliants to the police and Investigative Committee regarding "discreditation of Russian army" and "LGBT propaganda" online. She is a staunch supporter of the Russian military involvement in Ukraine.
In her 40s, she never was married and does not have children.
At the same time, Yekaterina Mizulina is immensely popular among the youth. Her appearances at universities always collect full conference halls. Students and pupils stay in long lines for her autographs and to take photos with her and shout her family name together when she appears.
To me this looks quite surreal because she is not a singer or performer. She is a state official in charge of tightening censorship in Internet.
The linked video says the most of her supporters did not reach the voting age yet. She has hundreds of thousnds of followers and young girls make Tik-Tok dedications to her.
On one meeting in Urals Univercity in Yekaterinburg, a guy aked her what she thinks about conscripts being useless in the modern war, to which re responded with insant threatening of him with criminal punishment fo "Discreditation of the Army", and was entirely supported by the whole hall.
So, my question is, what factors contribute to her popularity? To make the answers not being opinion-based, I would be glad for links to external analysis.
