Teach her about how muslims treat minorities. Tell her about every case of muslims kidnapping little Christian/jewish/hindu/sikh girls that you see on Jihadwatch etc. Eventually she might wake up to what islam really is.
You can’t teach her that islam is evil, but with enough examples of its evil she may realize it herself.
She is totally PC on everything, blacks, Jews, Orientals, gays etc. but it is the muslim angle that disturbs me.
Thanks for the suggestion.
