Sounds like you think it is the Ukrainian armed forces that have been exterminating people in Ukraine. Wake up. Reality is vey different to your dreams.
Actually regardless of Scott's ridiculous reasoning, it is actually true that Zelensky's approval ratings hit rock-bottom. This is why Zelensky refuses to conduct new elections because he knows that he is losing it 100%
As for why the people hate him, it isnt because of exterminating Ukrainians directly but rather indirectly.....
1- The high echelons in Ukraine have become more bold to the point of publicly embezzeling state money
2- The high echelons in Kiev carry out club and night parties every day while other cities in Ukraine are being ravaged by the Russian orcs day and night
3- Electrical outage in Ukraine reached up to 16 hours per day in some cities which is just outright ridiculous while Winter is on the way..... ofcourse it is because of Russian strikes but Zelensky after 2-3 years of warfare and he still cant protect his own infrastructure
4- Zelensky have been promoting Ukraine's performance in the war while in reality Russia is slowly but surely getting closer to its goals while half of Ukrainians left the country and the other half nearly lost 10-20% of its male population
Zelensky promoted his victory if the allies helped him, sadly even with the help of the so-called allies, Ukraine wont win. It is just impossible for a failed state of 30 million citizens to defeat a nation of 140 million citizens that has its own advanced domestic military capabilities and tooooons of natural resources that pour billions of dollara into its state coffers every day
