You are discounting linguistic imperialism.
Of course I am, that's what I'm arguing against - you're attempt to determine that an old understanding of altruism should be retained inviolate because... it used to be that way?
Which is naïve (because of Krauss IMHO)
You still haven't explained why, which is making it difficult for me to see why you don't agree.
and a little hypocritical vis the conflict definition of marriage. Where a new definition seeks destruction of an old definition.
A fail to see how 'marriage is between two people, who can be but don't have to be one man and one woman' some how 'destroys' a definition of 'marriage is between one man and one woman, except when it isn't but that's OK because that's in the Bible so it's different'. It's a modification, it's an update, it's an expansion, but destruction? Have there suddenly been no heterosexual couples marrying because the definition has been destroyed? I'm pretty sure the churches would have highlighted that loss of revenue by now.
Dawkins, Krauss and Dennett to me seek to impose their definitions and destroy all other ideas and definition. IMHO.
They make their case, and you're welcome to make yours. I'll admit, Dawkins confrontational style doesn't always lend itself to debate, he can come across as quite lecturing, but there are equally stilted communicators on all sides. Krauss seems, to me at least, to be quite open to discussion; the problem there is that it's a lot less of a subjective opinion, we've got measurements to show quantum fluctuations in otherwise 'empty' space: 'nothing' is potential, it's not a zero point.
Memetics is a case in point since it is an exercise in the subduction of other sociological ideas in the interest of the New Atheist portfolio.
Ah, 'New Atheist' - old atheism with less shame and more megaphones. Any sociological movement, any scientific movement, any religious movement is - in part - an attempt to gain credence for their definition of words. If you can control what words mean, you can control what people mean when they think, and therefore start to influence what they think. That's what debate is - trying to change what people think, by clarifying or codifying or defining words and inviting criticism of what words mean. That's one of the engines that drives that linguistic development, that and coming up with entirely new concepts that need to be fitted into an old language structure.
