You're projecting your sense of inferiority onto others as a sense of their superiority. Yes, atheistic humanism has been a superior worldview to Christianity, which I left as a young man, but in my estimation, it's superior to every other worldview? Does that make somebody like me feel superior for realizing this? In a sense, yes, but only in the sense that I feel fortunate to have escaped theism and religion. I also escaped a life of smoking by quitting young, which is analogous. Does having done that make me superior to a smoker? It's certainly a superior way to live, and probably inferior to having never smoked.
Yes, I take pride in being an atheist, a humanist, and a critical thinker. Why shouldn't I be? None of those just happens to people, and many if not most never achieve any of them. Religion is easy. Atheism takes some thought. It's not for everybody. It's easier to believe in a god than not. Being an atheist means that there is no devil to blame, no expectation of reuniting with deceased loved ones, no personal protection from the cosmos, only one life to live, personal responsibility for one's choices, nobody watching over you or answering your prayers, marginalization in a theistic society, and no easy explanations for our existence.
To the theist I say, try standing up like the bipedal ape you were born to be, and look out into the universe, which may be almost empty, and which may contain no gods at all. And then face and accept the very real possibility that we may be all there is for light years, that you may be vulnerable and not watched over. Accept the likelihood of your own mortality and finitude, of consciousness ending with death, of maybe not seeing the departed again.
Accept the reality of your likely insignificance everywhere but earth, and that you might be unloved except by those who know you - people, and maybe a few animals. Because as far as we know, that's how it is. And you will live a more authentic and comfortable life for having done so. Atheists don't worry about sin or hell or pleasing gods, don't believe false and unfalsifiable things by faith, and aren't asked to support religious bigotries, shun the world, praise anti-intellectualism, lust for an apocalypse, or hope for the eternal punishment of those who don't believe like they do.
