It is quite common to see bad geopolitical actors paying people to go online and accuse Westerners of being "Warmongers" or telling people who object to Putin's wars of imperialist aggression to "go and enlist and fight" with the subtext that the audience are weak and decadent Westerners with no stomach to fight a literal Mafiya-run fascist dictatorship.
Speaking strictly for myself, given that I want to avoid having people think I'm apologising for the Putin regime, I do not ever use these arguments in good faith.
Nope, that's not what I said. I'm a westerner, and it's not about "good faith". It has nothing to do with behind decadent or lazy.
It's because the modus operandi of war mongers, since before world war 1 has always been to agitate for wars that they don't want to fight for themselves. We are talking about nuclear war here, the bad faith argument is to imply that being against it is a sign of being a paid Russian shill. I guess the Pentagon is full of said shills, since they have never even hinted towards a direct war against Russia, or wanted to get directly (by means of troops on the ground) involved in one.
Now I agree that sometimes it's simply not realistic to go all "well do it yourself then". But in this case, Ukraine accepts, trains and equips volunteers. It's not a hypothetical.
