Camus famously broke with the french left over (certain aspects) of Algerian Liberation, for the simple reason that his mother continued to live there. He famously quipped:
"At this moment bombs are being planted in the trams in Algiers. My mother could be on one of those trams. If that is justice, I prefer my mother."
...which won him no small amount of censure. I always think of this moment when I am asked to co-sign, wholeheartedly, the measures endorsed by certain movements.
