From a liberal perspective what’s the difference between MLs having “critical support” for the Soviets or China and anarchists celebrating historical anarchists like Makhno and the CNT-FAI who burned churches and killed kulaks too? If anarchists are online supporting US foreign policy then liberals can assume you’re just a liberal and any claimed anarchism is just larping, but if anybody throws a brick through a Starbucks window that’s tankie authoritarianism stealing rights and freedoms from the Starbucks shareholders.
“Booby traps and other devices” is one legal thing, there’s no legal distinction. Pager bombs are always a war crime regardless of circumstances.
