Bullets to the head as a consequence of searching for socialism don't happen if you have grown up in North America.
That's certainly not historically true. In my neck of the woods, Ginger Goodwin is a good example of someone who took a bullet for being a socialist and resisting conscription during WW1.
And just because bullets are not used as much against the left in Canada these days doesn't mean contemporary anti-labour/left violence should be minimized or ignored. Maybe for some NDP lefties, the class struggle all seems a little surreal but (one example)I highly doubt the workers who struggled to (re)unionize Lakeside Packers in Brooks, Alberta would agree.
