Stack emissions are irrelevant to the overall point I first made, viz environmentalism being a quasi-religion....You're trying to move the goalposts.Keeping stack emissions to a safe level isn't the same as eugenics.
Eugenics has not been an issue for 100 years. Why muddy the waters with it now?
And if you think that eugenics isn't an issue lurking behind radical environmentalism, you need a reality check.
