Without comment on the general discussion...
The above quote is as much a representation of an ideologue as anything. The discussion has been on the interpretaion of theory and as such does not represent interpretation of proven fact. If the term ideologue can be applied to a theoretical interpretation, there are few within the theoretical physics community to which it would not apply.
We are all influenced by where we have been. We all see the world from a perspective that is defined by our past experience. Except to the extent that experience is supported by a consensus of imperical evidence – fact – everything we believe can be described as idealogy.., and thus each of us to some extend an idealologue.
I am happy to engage is some debate over the interpretation of physics. The very idea that wave-functions might be real is a shock to the ideology of some. But discussion and debate shouldn't lead to ad hominem and personal attacks. Nevertheless, there are some potentially very profound technological breakthroughs they are possible if wave-functions really do exist.
