What specifically is empty talk? Someone can support Ukraine for a number of reasons that don't require withdrawing from all life in a western nation. They might trust that their rulers have evaluated most alternatives before deploying military options and do not kill indiscriminately. You might scoff, but I suspect most people are at least somewhat in that boat; even if they think that the US shouldn't have invaded…
> murders of civilians were minimal. But nobody (AFAIK) is contesting that the US killed more civilians in Iraq or in Syria (or second-order in Libya) than Russia has killed in Ukraine. Your argument is that people perceive it as okay because the intentions were good? Our government could not forsee that these people would die, it was unexpected? Or were they unintended consequences that were foreseen? I don't believ…
That's missing the point. Nobody with knowledge of the matter is contesting that, but plenty of people lack that knowledge. This means that they're not willfully ignoring the kind of contradiction that would make their opinions about Ukraine "empty talk".
> Your argument is that people perceive it as okay because the intentions were good?
No, my opinion is that many people don't realize how objectionably the US has behaved in the past (and currently), so it's not apropos to call them out on a contradiction that invalidates their outlook on Russia's invasion. Call them out on ignorance all you like, though.
