From what little I unfortunately saw from him on twitter, this guy is the Russian equivalent of a hardcore Nazi.
What do you mean specifically?
"Dmitry Rogozin (Director General of Russia’s Roskosmos State Space Agency, former Deputy Prime Minister) – comments on his Twitter feed and Telegram channel (June 13, 2022)
“In general, what has grown up in the place of Ukraine is an existential threat to the Russian people, Russian history, Russian language and Russian civilization. If we do not put an end to them, as, unfortunately, our grandfathers did not do away with them, we will have to die, but end up at an even greater cost to our grandchildren. So let’s get this over with. Once and forever. For our grandchildren.”"

He also was a leader of right-wing party Rodina in early 2000s, see more details in Wikipedia:
>Under Rogozin, Rodina shifted towards the right wing of Russian politics and became the second largest and one of the country's most successful parties. A number of controversies on Rogozin's policies culminated in it being banned in 2005 from standing for election to the Moscow City Duma for using what was considered as chauvinist slogan 'Let's Clean the Garbage!'.
