Absolutely agreed. At some point it's just ethnoracism, masquerading as virtue-signaling.
"How does this action help end the war in Ukraine?" should be the litmus test, and if the logic to get there is too tortured, maybe rethink the action.
The other test is also, "How does this action help prevent Putin's next invasion?" Actions should not only be about applying pressure now, it's about destroying a literally imperialist government's ability to win its wars. So anything which undermines any aspect of the Russian economy is fair game. If we can keep them from training people, good. If we can keep them from raising taxes, good. If we can keep them from feeding their troops, good. If we can usher in strikes over unpaid wages, good. If East European stores stop importing Russian goods, good.
