I have a great respect for Sam Harris and his use of language and his ability to describe. I think it's just blanket statement to say he is unfairly treating Islam. He points out that to the very core Islam is a religion concerned with converting all other people, on pain of death, and that any version of Islam you see who has gotten around that is just making up their own interpretation of things. He is right, just as Jews and Christians have today their own evolved memes of religion, Islam is at it's heart a religion of war that can be presented in the light of peace.
SE Cupp I loathe and think she is nothing but a professional troll capitalizing on controversy and arguments she instigates.
Penn Jillette I like, though his politics I think are naive. I think he is right that we should give people more credit than we do for being naturally altruistic, but I think he underestimates what ignorance and selfishness can do when left unchecked.
Bill Maher I can't stand, but I love his show. He's like a very annoying teenager who just discovered the latest finding he can champion as bolstering his identity, and his criticism of modern medicine is just sheer stupid.
Ayaan Hirsi Ali, I don't know enough about.
