Of course, the lefties will argue that Canada was correct to welcome his parents into Canada, regardless of their enmity towards our country and our way of life.  They will even argue that attempts to identify potential immigrants who hold such values is somehow "un-Canadian."

What is it about leftists that causes them to be wilfully blind to facts?  How can even a leftist deny the outcome of letting hard-core Jihadists such as the Khadrs, into our country to wreak their havoc upon their own children as well as upon the rest of us?
