I disagree. While my statement did not include any kind of elaboration. This is not a simplification.
At the very least a strong majority (and I am being conservative) support the annexation of Ukrainian territories and elimination of Ukrainian culture and language in areas under occupation. On the quantitative side this is confirmed by various polling initiatives that use different methodologies (including in-direct polling with attempts to estimate preference falsification).
On the qualitative side, you can look at genocides committed in the last ~100 years by the russians (and there are several, includes less well known ones) and review the attitudes towards these crimes among various socio-political groups (not necessarily in a purely quantitative manner).
I have one interesting anecdote. Currently among the "liberal" russian opposition there is a big debate around a 3 hour YT series about the 90s in russia.
One bit topic that was completely excluded was the actions of russians in Chechnya; the creators (Navalniy's organization) said it was out of scope.
During their intervention in Chechnya in the 90s, they killed approximately 5% of the civilian population; it would be like if 7.5 million russian civilians were killed.
Don't get me wrong, a relatively small % of russians would openly admit to that they support extermination of Ukrainian identity (still 10s of millions). But even among the reminder, there is a strong undercurrent of supremacism, a desire of expansion that de facto is support for genocide.
