Can an Atheist know anything?

[Nineteen]

No knowledge of your holy book is required to judge what is done in its name. That isn't to say no virtuous person could be a Muslim. But for the great majority of Muslims, it doesn't seem to be working.

Do you really believe in what you say ? Islam is not a company and muslims are not its salaried-contractual personnels . So in this case I can blame all the atheists because of some atheists ? Now I'm sure personal interests will be engaged and you will say just the opposite for yourself .
