Just went from what you posted for example:Aaaaaaand....what evidence and calculations would those be?
The OP asks for conclusions about Ms Thurnberg, specifically if she is deeply disturbed or a brave campaigner. I assume the OP is either requesting clairvoyance, long-distance psychoanalysis, or ...just possibly... opinions.
Can we further assume that you are not asking for evidence and calculations, and that you are pulling out the famed ISF 'Scientific Rigor Only When Convenient And Utterly Inapplicable' card?
Please specify what 'calculations' are appropriate for me to have an opinion.
.....Again, if her mission is the lowered carbon footprint, how much more is she wasting rather than jump on a flight's available seat? That's the cold math at play, that an actual advocate would factor in.....
I'd like to see that "cold math".
