I'm pretty sure they're burying Ukrainians because they're invading Ukraine. If they want to avoid diseases they can stay home. There are photos of dead civilians in the streets.
"Fighting FOR Mariupol" is more accurately stated as "wantonly destroying the homes and infrastructure of a thriving Ukrainian city, whilst murdering and raping civilians, and stealing their property".
What's wrong with Kherson? It's occupied by Russia since the beginning of March. Is there any news about the outrages of the Russian army? Destroyed buildings and infrastructure? I'm really curious. Russian propaganda said that the city is preparing for a referendum and silent about the protests of civilians.
I've seen video of a lot of protests in the main square. They have been happening since the first occupation. I would describe the size of the crowds as being in the thousands. To be honest, it's not a city I have followed closely - but there was at least one protestor shot (not killed) by the Russian soldiers. A referendum at this time would not be considered very legitimate, given the circumstances.
