The following statements might be all true at the same time

• USSR committed imperialist massacres
• USA committed imperialist massacres
• most of the Western European nations committed imperialist massacres

No one’s refuting that ‘both sides’ logic. But if

• I took a beer from the 2-4 in your garage
• Pierre took a beer from the 2-4 in your garage
• Ivan took 22 beers from the 2-4 in your garage

Then we’re all bad house guests, but Ivan’s a complete asshole.
