Unfortunately, that says more about American discussion - America has moved beyond left Vs right to reality Vs “alternative facts”. For example, climate change denialism, large vaccines cause autism, the election fraud nonsense. Unfortunately, given that opportunistic morons like America’s republican party have politicised and denied climate change, I’m sure they’ll be a segment of the population that will blame anything, including Greta.
So yes, I do agree with you that the large anti science wing of America wouldn’t warm to her, but they never would have.
