Yes, there are extremists in Ukraine. Azov (and others) was this before the war, they where also a political party that did not get enough votes for a single seat in Ukrainian parlement.
And Azov started to militarize.. after the Russian invasion in 2014 as counter weight to Girkin and his extremists who dragged Ukraine into a war.
So what is your point? A whole state is defined by its extremist minority? Ukraine does not have the luxury to crack down on or exclude these groups now they are in an existential battle for survival.
