Why this attack on "Python folks" when the comment you replied to never mentioned Python? Got a bee on your bonnet?
It is true the blog post does not mention Python. However, if you should pick one "opiniated" language in the same niche as Ruby, this is the one most people would pick.
'There should be one-- and preferably only one --obvious way to do it.' from http://www.python.org/dev/peps/pep-0020/ a sentiment that is re-enforced by the python community and even used to pitch python as an easier language since there is only one (right) way.
The whole "opinionated" thing is a bit silly really. Ruby isn't all that opinionated, as the GP poster says. Why Python people would get their bee in a bonnet over "opinionated" code is somewhat beyond me. After all, Python is a language where whitespace is significant...
