Is it almost impossible to have a secular conversation in Arabic?

The Islamic religion has insinuated itself so deep into Arabic culture that it's very difficult to have a normal conversation in Arabic without saying something about Allah the imaginary god of Islam, right? For example, if you wanted to say something like, "Goodbye and I hope I see you again," it becomes, "Goodbye and God willing, we will meet again." You know, you can't say just normal secular things. This means it's going to be a very long time before Arabic people will become secular and rational like other people in the world, right? The Arabic culture, because of all the insane religious nonsense that is so much a part of it, will be in this state of arrested development for a long time to come, don’t you think so?
