David Thompson on "protests" by college students in the UK:
One enormous placard read, “We are not your slaves!” An odd sentiment, really, from people so engorged with entitlement they assume an almost aristocratic right to other people’s labour and other people’s earnings. A more honest placard might have read, “You will pay for things I want or I’ll smash up your stuff.” But that would sound like extortion more than slavery.
Thuggery has a long and proud tradition on the left. Violence is perfectly fine as long as the cause is "just".
