Bowker got it wrong in at least a few of the above. He didn't seem to take caution in how he expressed his view, nor where it was broadcast.
His words were blunt to the point of callous and in posting them on Sir Ian's LinkedIn account, with more than 2500 followers, Bowker effectively sprayed his view across a large group who were highly likely to be offended.
In his original post, respected Māori entepreneur Sir Ian praised a cartoon which, incidentally, showed DNA intertwined from the wakes of a Māori waka and a European-style ship. To consider this as "another example of European NZers not being proud of their own ancestors" indicates an incompehensible sense of twisted privilege.
In any case, to praise one group does not denigrate another. One wonders whether he has been emboldened by politically-motivated drums recently being beaten with claims of a cultural war.
Bowker should button his lip while he works on realigning himself with - if not modern thinking, then - how to express his views in a civilised manner.
