the story that Russia is kidnapping Ukrainian children and Russifying them

I don’t doubt there might be isolated instances of this, but libs are going off of Ukrainian war-time propaganda. You can be explicit about it with them: what is the primary source for your claim? Inevitably after 4 times of back and forth explaining what a primary source is, they’ll go to the website made by the Ukrainian gvt where they show the supposed tens of thousands of kidnapped kids. There is a UN report talking about the topic and if memory doesn’t fail, the actual confirmed number is about 300 total. There is no journalistic work proving anything remotely similar to the tens of thousands number, no primary evidence, just a number on a website. That’s literally all it takes.
