One can only (bitterly) laugh at your cluelessness and ignorance. After all, they relieved you of the burden to listen to the sides involved, with the complicity of the media and various "dangs". You know, "Russian propaganda", "Prigozhin troll factories", or whatever convinces your "critical" minds.
