Has atheism became a trend?

I'll start off by saying that I'm an atheist myself. I once believed in God. Now I'll say that I have encountered many people who declare themselves atheist. I ask them why and they provide me with answers that are very shaky, with incoherent arguments. I've noticed this more among the youth. Its as if its perceived that labeling oneself as atheist makes you original, hip, or rebelious, as if they want to stand out from the crowd.
