My way to shut up the Left is to tell them about my experiences in Hong Kong during the 1967 Communist riots inspired by the Great Proletarian Cultural Revolution in next-door China. Can’t refute that!
Wow. I kept up with the Red Guards depredations against the Chinese people from 1966 on (I was in college). Sheer barbarism inspired by Quotations from Chairman Mao.
Didn’t know it spilled over into Hong Kong.
There was a New Yorker cartoon that year showing Red Guards milling about as one shouts,
“I denounce Comrade Wong! His little red book is filled with names and addresses of girl comrades!”
