If, as the writer seems to believe, that Canada only wanted white Protestants, how does she explain that White Protestants are a minority in this country today? As a white, non Protestant, I am shocked that they allowed me to enter 44 years ago - I am so grateful that they seem to have made an exception for me.
What she fails to understand is that the immigration policy in this country prior to Pierre Trudeau was based on need (that being need of the country for certain skills) and did not discriminate. My citizenship ceremony (40 years ago) was a virtual United Nations and I don't think that anybody knew or cared about anybody's religion or race.   
Of course, she can play her card and continue to retain whatever chip on her shoulder she arrived here with, but it would be nice if she just moved on and if she realized that the only racist and religious bigot in the room is her. 
On the other hand we can apologize to her like I seem to do for all my ancestors who did not live here.
