I haven’t seen Bill Nye Saves the World but the main problems people have with him is that he’s harsh on climate change deniers and he differentiates sex and gender.
The problems I have with both NDT and Nye are that they should stick to teaching science and quit dumping their opinions about philosophical and cultural matters. It’s like they can assert, because they are science celebrities, other not-scientific random crap they opine.
Just like you and I can assert, because we log on to a forum, other not-relevant-to-our-respective-day-jobs random crap that we opine!
I seriously have no idea what the problem is here.
