That is a gross oversimplification on a couple of counts. The founders of our country grew up with religion as a part of education and were okay with it, but that's a far cry from religion DICTATING education: the point of my meme.
Secondly, Islam is as complex as Christianity and neither better nor worse. Muslim leaders founded great centers of learning in the middle ages, preserved and extended the knowledge of ancient civilizations (especially in the areas of medicine, astronomy and math). Muslim fundamentalists have (in the past and the present) done terrible things: massacres and destruction of cultural treasures. And I could have written that exact series of sentences with the word "Christian" in place of "Muslim" and it would be equally true, except for the part about medicine, astronomy and math.
