It probably won't change your mind, but here is a pretty transparent poll on a mix of Russians at a train station in Moscow (to capture some from outside the metropolises). The multi hour poll is a continuous video to show lack of selection bias (parts with no speech are fast forwarded)

About half the Russians don't support the war. I hope the conflict ends soon.
Lack of selection bias would be selecting according to demography distribution. Looks like this sample has young people way overrepresented, by clikcing through a video. And young people support the war slightly less.
