Some of us pretend that there isn't evidence that contradicts the Christian god, but there is. There isn't evidence that contradicts a general, vague sort of god, but I don't see how such evidence could disprove something so vague. but regarding the story of Christianity, there are obviously very important stories there that have been cleanly disproven, and these stories are central and critical to Christianity actually being true, which it cannot be.
I can't say that there is no god and I have no desire to say such a thing. That would limit my freedom to think by forcing a disbelief. But with regard to Christianity and the Christian god, I can say confidently that it isn't true and that particular god doesn't exist, just as confidently as I can claim knowledge about anything else imaginary, including other ridiculous religions. No need to pretend like Christianity hasn't been debunked.
