"All Scientists Should Be Militant Atheists"

[ScepticOrganism]

I fully agree as well. If anything, it should be mandatory.

You don't think a non atheist should be allowed to be a scientist? This seems a little unreasonable. The scientist who first presented the idea of the Big Bang was a Catholic priest.

I think that scientists, however religious they may be, tend to flirt with the idea of atheism more often than they'd like to admit, in the face of evidence and reason. 

It can create a deep inner conflict within them, and some never fully recover from it. I don't think that your first question can be answered with a simple yes or no. I am very tempted to say yes, but reality suggests otherwise. 
Don't get me wrong, I would love to live in a world where science is fully independent from religion. But we live in a different reality. So it would be, as you've said, "a little unreasonable" of me to think that.

As to your second assertion, I highly doubt that he came to that conclusion through his beliefs. I hope that you're not insinuating it. But I've been surprised plenty of times. Perhaps you're just using it to reinforce your first argument, which I've already answered in the first paragraph.
