Sadly, I'm not that young -- I'm about 50.
Absolutely, older Russians ("The TV people" as we call them here) did support Putin before the war. However, I haven't yet formed my opinion about what they think now. Remember, they've been raised during the Soviet era, when Ukraine was considered one of the brother nations to Russia, who fought together with us against Hitler. And now we're bombing their cities -- we're the Hitler now.
Maybe they'll go into denial ("NATO hates us and forced us to do it"). Maybe. Also, their life quality will severely degrade in the coming months -- they'll have to spend much more money on food and medicine; and that would also be a factor.
