You're talking about exoteric, monotheistic, fundamentalist religions. Those are indeed absolutist and simple-minded, since they reduce God to some self-contradictory idol, which they defend fallaciously. Atheists are justified in tearing down such unworthy faiths, as I've attempted to do in numerous writings.
The Eastern religions don't proselytize so much and aren't as defensive as the Western monotheistic ones.
You say you've outgrown the desire for a deity. I have too if we're talking about a personal, transcendent creator of the natural universe.
But have you outgrown an interest in the sacred? Or have you merely presupposed the merit of your deepest values? Religious faith can be defined as ultimate commitment. Can we justify those commitments in life by appealing strictly to reason? Or do we atheists have religious (Luciferian or Faustian) faith in reason, technology, and human progress? Isn't that our civil religion, which we call "modernity"?
The existential and pragmatic question, then, is whether, say, Christianity is superior not to mere atheism but to the atheist's positive worldview which counts as a secular faith.
