That's because it is
intended to be pejorative. Good job! You get a cookie.
Yeah, here's the thing. The science is settled.
There is no reasonable doubt about the fact that human activity is causing the climate to change in a way that is already harmful to lots of human beings, and other organisms.
The deniers are in the same position as those who proclaim that cigarettes are carcinogenic, or that the Earth is flat, or that vaccines cause autism. Yes, the science which proves AGW really is that solid.
Thus, it is the climate change deniers who are not interested in facts or science or reasonable debate. They're partisans who deny facts to push their ideological preferences. That's why they spend so much time and effort deliberately misrepresenting the solutions, engaging in
ad hominem attacks on climate scientists and activists, vainly attacking the data, and citing anything they can -- no matter how irrational or contradictory -- to try and "score points."
And yeah, we've seen all this before. The deniers are using the same tactics as employed by the cigarette industry, or opposition to earlier environmental movements. There's even some overlap in the individuals who were recruited by multinational corporations to sow fear, uncertainty and doubt in order to fend off regulation and responsibility. (

If you're looking for someone who is uninterested in science and dogmatic about climate change, maybe you ought to look in the mirror.
