If you have 41 minutes to spare, this rant from a theoretical physicist does a good job explaining why people react negatively to the publicity surrounding the space tourism launch.
A lot of it boils down to the fact that women have been instrumental in traditional space programs all along. Publicizing passengers on a tourism flight as if they are pushing boundaries is insulting to all the professionals who dedicated their careers to actually expanding boundaries. They aren’t even the first all women crew as claimed. Valentina Vladimirovna Tereshkova flew a solo mission on Vostok 6 in 1963
The media messaging on the flight has been terrible and regressive. Complaining about that isn’t misogynistic.
People focus on Katy Perry as representative of the whole stunt, because she has been portrayed as the main figure all along.
They literally pulled a Katy Perry et al. Do you think that framing just happened without any input from KP and her publicists? Did Katy Perry use her ample airtime to credit all the female engineers that actually worked for years made the flight happen, or to correct notions about the flight not actually accomplishing any significant firsts? Katy Perry gladly took the center of the media spotlight, so naturally people use her image as emblematic when ridiculing the stunt. She is a vapid celebrity doing annoying celebrity messaging like “making space and science glam.”
Katy Perry is an eager participant in the outrageous messaging around the flight. She earned the ridicule, not by being a woman, but by acting ridiculously.
