No, most muslims aren't radical. Especially not the ones that are US citizens. But keep up with that shit and more of them will certainly accommodate you.
How do you know most aren't radical, how do you actually know what's in their hearts and minds....are you psychic? Tony Blair today said that support for ISIL/ISIS/Daesh runs deep in the Muslim community. I don't often agree with Blair, but I think he's correct.
Have you personally kept tabs on ALL Muslims, are you privately listening in to what ALL of them are saying? No and no.
Therefore how do we know that publically they say "oh this is awful", but privately they agree with it and then praise Allah.
Are we to trust ANY of them anymore, when even the women are out there shooting people and blowing themselves up?
