'To remove the perceived stigma, we would need to have more scientists talking openly about issues of religion, where such issues are particularly relevant to their discipline.'
How often is religion relevant to a field of science where it needs to be discussed? Really, religion is inappropriate to discuss in scientific terms, as the entire point of religion is blind faith. Science has no place in religion, just as religion has no place in science (as in, "God did it" as a valid hypothesis, not as in the scientist's personal belief structures, which they are more than entitled to and I know many scientists who are also theists).
