It takes a twisted mind to believe that families worshipping peacefully in their mosques are "invaders," and that those who slaughter them are righteous protectors.
But there are people who believe that. Ones who actually unleash violence are rare. Much more common are those who goad them to it and cheer them for it. There are also, increasingly, political leaders who lend respectability to the idea that white Christians are the only legitimate citizens and residents of the United States and many European nations.
This way of thinking is deadly poison. Those who denounce the shocking violence while helping normalize the creed are dangerous, despicable hypocrites.
