This is their rationale
"Before that happens, it might be worth asking yourself, since it is getting pretty serious: What is this really about? Why do I hate Putin so much? Has Putin ever called me a racist? Has he threatened to get me fired for disagreeing with him? Has he shipped every middle-class job in my town to Russia? Did he manufacture a worldwide pandemic that wrecked my business and kept me indoors for two years? Is he teaching my children to embrace racial discrimination? Is he making fentanyl? Is he trying to snuff out Christianity? Does he eat dogs?"
I wonder if their support remains after Putin threatened nuclear retaliation if the West interferes?
