shouldn't we really stop the whining between the scientific and religious factions?
look: if there are scientists (as you say) with blind faith in unprovable beliefs, then they're not being scientific but religious. in this case you are asking to stop the whining between religious factions, and that would be for them to decide. i guess they won't, not because they're religious but because they're factions. religion is ok if (and only if) one limits it's application strictly to oneself.
what these guys are speculating may seem weird but is the effort of theorizing possible explanations for concrete contradictions which need one, because there is a necessity to explain those to progress in our understanding of the world. it's work in progress, sometimes you do have to examine weird possibliities so you eventually find the right track.
classic religion, in contrast, assembles theories equally fantastic which are no necessary explanation for anything (last time i checked), and that makes sense because (most) religion actually doesn't seek to explain, but to people to live happily and stop asking.
if you then throw those "who don't want to know" into factions and confront them then yes, real shit starts to happen, and "whining" is the least concern.
