Late in his life, Simon reflected upon the extensive ad hominen attacks he had received and he wrote:
'One cannot argue with personal attacks. One can, however, attempt to explain them. Concerning the purpose of the attacks, I see them as a device for marginalizing, devilizing, and thereby dismissing from consideration people like me so that their ideas should not be taken seriously.' (Simon: A reply to my critics)
I am especially frustrated when environment "goes Hollywood" -- usually when a well-meaning celebrity "discover" an issue, lends their name and media currency to promoting "greater awareness" of that issue. Since the main expertise of any celebrity is media manipulation, it is unsurprising that celebrity endorsement of any environmental issue usually has more than a smidgen of hype, exaggeration and mis-understanding attached to it.
This link from the World Climate Report shows that celebrities are often guilty of hypocrisy -- asking others to do what they themselves do not. In this case, a minor celeb is questioning the personal scientific credentials of a well-known climate change sceptic, when she herself has no formal science background. Truly galling.
Its at times like these you remember what your grandmother taught you as a child: "people in glass houses shouldn't throw bricks".
