So 'collective punishment' is already happening.
All this bullshit is already affecting our lives. We're not part of any Muslim community, but my wife has a Muslim name, and public photos exist of my Muslim wedding. My wife's been told to leave the country by a red-neck. I've seen confederate flags flying here (in Canada...). Up until recent events, Canada's been pretty tolerant. Now it's anything but. It's getting harder to play down terrorist attacks as simply an 'aberration' or an 'isolated incident'.
I'm being real, talking about real things. France woke up to the FN leading the elections. Hollande closing down a few Mosques and banning religious symbols is small potatoes compared to could happen in the not to distant future... Maybe I'm sensationalist and too controversial. I prefer the socialist dream to the conservative dream. But right now we're headed towards a bleak future...
It shouldn't be hard to see why. Imagine reading HN and hearing your fellow users call for you to be punished for crimes you are at least as aghast at, and personally more likely to suffer from, than the rest of the HN population is.
