There's this assumption going on here that when the Russians say <a number> with regard to the children, all of those were stolen from their parents at gunpoint.
Except, yes, that is almost entirely exactly what it is. If not outright kidnapped then kept indefinitely after they were supposed to be home. Do you actually think these Russians are running some sort of usual summer camp?

You should sort by Top, not by New.
Except, yes, that is almost entirely exactly what it is.
You have two numbers here: 19,5k and 700k. The former is Ukraine's government's number for those they consider illegally deported. The latter is the number Moscow recently said they're hosting. You can see the disjoint here, right? The 700k would include all the nominally Ukrainian children that on the outbreak of the full-scale war went with their willing, pro-Russian mothers, to Russia. Which was by far in the top destinations for refugees from the start, remember? These children were not stolen - their families always wanted to be Russian, thought of themselves as Russian, welcomed Russia, and thought they'd be better off in Russia.
So, in the context of those numbers, taken at face value - no, that is almost entirely exactly not what it is.
The circumstance of Russia being the most popular destination for refugees from the eastern regions is a little undermined by the fact that Russia blocked and/or bombed humanitarian corridors to western Ukraine.
All this about supposed longing for unification with the Russian Motherland that people in the eastern regions supposedly always felt themselves to be part of (and the thread follows, have been stopped by Ukrainian nationalists) is manufactured by the Kremlin. Even before the invasion in full scale, which I will remind you decimated the popularity of any remaining Russia-favoring political currents, only 22 percent of the Luhansk oblast favored reunification with Russia in 2021.
https://carnegieendowment.org/politika/88542 This is despite Russia-favorable informational restrictions put in place by the occupation. After the full-scale invasion, support for Russia evaporated in these regions.
The 700000 number, it seems, comes from an official pronouncement of the Kremlin and is likely made up to cast an image of themselves as saviors of children because their positions of moral reasoning are different from ours. Whatever the reason for Ukrainian children being sent to Russian camps, to say it is just because all their parents thought of themselves as Russian all along, is demonstrably wrong and is a dangerous attitude to have.
