> Why do so many nuclear fans try to suggest climate change only exists if you like nuclear? It's very odd.

You’re putting the answer you want to hear (“because they are nuclear fans”) in the question, making it extremely obvious but then stating it is “odd”, as if the answer wasn’t straight forward.

Disingenuous – is the word describing this, I believe.

Also you need to check your concepts. “Climate change” is what we want to prevent (more like catastrophe, really, by now).
