I posit that the crimean question will also unnecessarily put in the same cohort all those people who do recognize the distinct culture of Ukraine and their right of self determination but also consider the past and present situation of crimea to be more nuanced.
EDIT: some Russians may recognize that Ukrainians have right to self determination but they may also recognize that today Crimea is populated by a vast majority of Russians and thus there giving that land back to Ukraine would lead to further bloodshed. And yes I have heard actual Russians having that position (I'm not Russian fwiw)
