You see, Roy doesn't like the word "denier" which he reckons is forever linked with the idea of Holocaust denial which is beyond the pale. Well, Roy, here's some news for you. Language changes, words alter meanings or get associated with different ideas all the time.

Denier also has a history. It is a small medieval coin, a measure of the weave of fibres, a person who contradicts established ideas, a small trifling sum. So perhaps that last definition is the sense in which we should use the word in the context of those that deny climate change in one or more of its forms.
I think the point is made. Read Spencer's rambling (meaning = jewellery for sheep) and you will find some political rant rather. Perhaps he should get out more.
