Arab sunni muslims in Sinjar raped, sold and murdered their own non-muslim neighbours as soon as ISIS strolled into town. They weren't forced, they were greeting them with open arms evident by photos.
I don't like to entertain the notion about whitewashing ISIS as some sort of a sensible "muslim alternative", not that I'm accusing you to suggest that. I'm just noticing that pattern here more and more, some serious high level of naivety of people who've never experienced living in those areas and conditions.
Both Lee Kuan Yew and Pim Fortuyn are gone. Not much hope left.
