Atheism is itself a belief. Thus, do not bash believers. Treat their belief as yours: an idea of how the world may work that is certain to you but uncertain to all else.
Furthermore, know that atheism is not superior, it’s just another worldview. Perhaps it means you have forsaken magic and fantasy as reason for our world; but it does not grant you some sort of superiority. What it does grant you is a burden, the burden of knowing that you do not know, and you seek knowledge without hindrance of preconceptions. Which comes to a problem you’ll need to figure out: are you atheist or agnostic? Atheist means you do not believe there can be any sort of theos, or god. Agnostic means you don’t know to the point you don’t believe in any common worldview. This is an apples-to-oranges comparison but vital to understanding where you stand.
All in all, being a proper atheist means you have a lot of work to do. Not only do you need to find myriad counter arguments for theism, but you need to justify your atheism. Thus, you should actually be agnostic. That is: aware that you do not know absolutely. Use this golden mindset to your advantage and engage the world with an open but skeptical mind.
You are now a learner, not a knower. A grower. And yes, indeed, a shower, when shows are shown in the shower.
