Many on this board and in many right wing communities have a tendency to deride climate change - either by saying it's not happening or that it isn't manmade. The issue is that it is, in my opinion which I hold strongly, both real and man-made.
Why then, are so many right-wing groups against climate change?
This is what I call the poison pill of the right wing. It is, in essence, a way to make sure that true nationalism is unelectable. By making sure that the further you go right, the more environmentalism is derided and hated, the more you make sure that anyone who is aware and cares about the issue has to make a moral choice between the destruction of their own country (and let's be honest, in most cases, normies don't even see it that badly - which makes things even more one sided) and the destruction of the planet (which is obviously backed by state and school indoctrination - not a bad thing, but you can see where this is going when the left is the only one generally explicitely environmentalist in european countries).
This, in my opinion, is evidence that currently, most right wing groups are controlled opposition to discredit the right wing as "rural and suburban retards" or at the very least nudged in that direction. This is bad all around - it only deepens the voterbase that cares more about the nation than climate issues into being biased to hate environmentalism, leading to more misinformation and essentially cornering the already small (in many cases) right wing into a corner - either follow the climate change denial or lose voters.
