Mr GumnutYour post has a religious tone to it, calling people "deniers" who don't agree with you, why not call them "infidels" or "unbelievers" and blow em up or burn em at the stake.
I could use longhand and each time refer to one or any number of people who "deny" that there is any substance to the science that supports human-induced global warming theory, or I could call them "deniers"; the latter being my preference.
You do know this anyway, and simply wish to stir the pot, as I see is your want.
I find that most deniers simply regurgitate falsehoods and myths that abound the popular media. A lesser number look at the evidence, don't understand it, and come to wrongheaded conclusions. If their beliefs are poorly based, it is possible they might change. On the other hand, there are some who quite deliberately choose information to obfuscate the facts and mislead. It would be an error of judgement to call them infidels or unbelievers as they have a special agenda. Do you wish to elaborate yours?
