When a Barrie, Ontario city councillor wrote a long post criticizing two local MPs for "playing footsies with white supremacists" he might have been expecting some pushback. But nobody thought it would end in two defamation suits, an official reprimand and a long and passionate council meeting. Keenan Aylwin's story is one that's probably going to happen elsewhere as election rhetoric heats up. With white supremacists becoming increasingly unafraid to voice their opinions in public, what duty do politicians have to disavow their support? And if they don't, what can those politicians' opponents do about it? GUEST: Fatima Syed, National Observer
