@ddancom,
I think I've lost the thread of your point in here somewhere Didymos, but you did say it was pro-evolution extremists who directed hate speech at the religious (who were just beginning to think about higher criticism and the cutting edge scientific discoveries) - and it did seem to me that you were trying to ascribe the sad beginnings of this history of contention to hateful and hurtful remarks from said extremists.
This does seem a rather bias view. I admit that my own bias is the other way - but I would be willing to concede that there has always been tension between certain zealous types from both sides of the arguement about whether or not god is required in a model of life, the universe and everything.
To recontextualise - the OP asked whether or not scientific progress is hindered by religious debate. He also seems to me to pretty squarely blame Dawkins and his ilk on the recent tensions.
LIES!
I personally think Dawkins is motivated by various factors (including money and fame), and that some of his stunts are a bit naive. However, I do understand how angry he gets due to the fact the certain religious figures get away with lying about science, and indeed succeed in convincing many of their followers of the same lies.
Now when I say lies I don't mean the many apt criticisms of certain scientific theories that people have raised. Challenging theory is the only way to test whether or not it is sound. There are many anti-evolution pundits who limit themselves to attacking loose ends or weak links in the theory. Whilst I think they are missing the wood for the trees myself I actually think they provide a service and attack it in the only really adult fashion.
I think those who lie about it or, even worse, attempt to twist it to suit scripture, end up debasing both religion or science. In lying they decieve their followers and deny genuine discoverers due credit - which seems to me to undermine religion's claim to be an agent of moral tutelage (which I think is false anyway - but to so blatantly prove me right is clearly counter-productive).
UNECESSARY BELLIGERANCE!
On the other hand I have seen plenty of evolutionary pundits berate people for "just not getting" an admittedly complex theory about which there is a deal of controversy even amongst those who support it (cf - arguements between Dawkins and Gould on punctuated equilibrium, arguments about whether there is a tree of life or a web, arguements about how the components of cells came together, and so on).
Perhaps an illustration of this comes from Christopher Hitchens' position "who could look at the view through the Hubble telescope and still be impressed by the Burning Bush?"
Well, me for one - because I like folklore and mythology and don't much care for cosmology. I just find it a bit dull. That's just me. So what?
So I do see how pundits from one side can be just as off-putting as those from another.
The mutual threat is the real issue.
IN THE RED CORNER
Those who believe that the power of the bible comes from whether or not it is the literal word of god will obviously want to see scientific theories to the contrary discredited.
They are of course allied with those who make money from religion, who have a business interest in:
* Formenting discord.
* Giving their followers an enemy.
* Making converts.
* Having issues they can become dramatic about (moderation does not make for good copy).
* Giving people who are not able to take comfort from complicated godless answers a simple godly answer.
IN THE BLUE CORNER
Pundits for evolution are frightened of having the most sound of scientific theories taught alongside creationist theories, which - frankly - belong solely in RE classes.
There are of course, those who profit from the teaching of evolution, and they would be just as motivated by greed and the need for converts and a certain level of hysteria as business minded anti-evolutionists.
IT'S THE FAULT OF THE MEDIA ANYWAY
And, as always, the media gives voice to the extremes of the debate (moderation does not make good copy - given a choice between a fight and near consensus most people will want to watch the former).
