Ban Muslim immigration to Canada.
In fact, let's just ban Muslim immigration to the west altogether.
Think of the many female lives we can save by doing so.
Look, Canada is guilt-tripped over the memory of the S.S. St. Louis. This was the turning away of a passenger ship full of Jewish refugees fleeing pre-war antisemitism in Germany in 1939. After being rejected by Cuba, the U.S., and eventually Canada the ship had little choice but to return to Europe.
The Jewish refugees were eventually resettled in various European states outside of Germany but war broke out, Germany invaded, the Jews were rounded up, were sent to concentration camps and ultimately to their deaths. Presumably most of the passengers of the S.S. St. Louis were among those captured and executed. And since Canada turned the ship away the nation is somehow to blame for their deaths, or so it is implied.
So following that line of thinking Canada is complicit in the deaths of these Muslim women. Had we refused them entry and they stayed in their Muslim societies they'd never have been corrupted by western influences, would have remained good Muslims, and would still be alive today.
So, in a sense we forced the hands of their killers. Because of their culture (and remember all cultures are equal) the women had to be corrected with the most capital of punishments.
Canada killed them.
So, to prevent future deaths of innocent Muslim women in Canada we should ban Muslim immigration outright.
Hell, it's not like Islam has anything to offer Canadian society anyway so what have we got to lose? And we get to save the lives of so many Muslim women. So, Canada doesn't lose anything of value and Muslim women don't lose their lives. It's win/win!
