I do not think it is possible to adequately explain such nuanced issues to such a smooth brained individual in this format.
Your false equivalency reveals either your ignorance or biases, perhaps a bit of both.
A discussion of this topic requires first clarifying for you how each war is different, and how the global political and historical contexts are vastly different, as are the political and cultural realities of America in both periods.
Explaining all of this context for both wars and the associated protests would take a very long time as it would likely require tearing down deeply ingrained assumptions you have on both conflicts, as well as the protests. There is likely a lot of geopolitical history of both regions, and the roles played by all the players in the history of the regions and associated conflicts.
This is only a start.
Or you could continue pretending that saying we should let Russia have as much of Ukraine as they want is the same as saying the United States should not be sacrificing a generation of young men for what had been an ideological proxy war.
EDIT: someone smarter than a turnip wrote the above rant. I hope someone dumber than a bag of hammers reads it and understands a quarter of it.
