You seem to have a whole theory about what’s up, and it might even be right. Or it might not.
That’s the point. Nothing here is falsifiable, and the subject is inflammatory, so your chances of getting a productive discussion are approximately zero.
Move on.
It’s no secret that Ukraine has conscription. It’s a country at war, because it’s been invaded. Wartime rules therefore apply. This is also why the election has been postponed, automatically and legally. Historically, many countries have had peacetime conscription. The UK had it until the 1960s for example, France’s until the late 90s.
Ukraine had conscription for only for 27-and-overs until recently. It’s now 25.
None of this is a secret.
Since you seem especially concerned about the moral aspects of the subject, and cite scandalous abuses, the question is unavoidable: why you are so exercised by Ukraine’s situation when Russia is far, far, far worse on all these fronts? It’s odd.
