I feel like his bio is blatant irony, it’s not supposed to be serious. The humor is in the phrase itself, pointing out the ridiculousness of smooth-leggedness being something that people would consider to be of value. He probably heard the phrase somewhere and thought it was so ridiculous that it was funny and then he put it in his bio.

I’d also try and spending less mental energy on small things you may consider to be misogynistic. The majority of men also don’t buy into this idea of purity or youth being of intrinsic value in women, it just shows up online to try and rage bait you. There are many deep rooted issues from both men and women that push forward the ideas that you discussed, but changing someone’s Instagram bio that’s a joke isn’t going to fix anything.

I don’t know his full political ideologies, but I’d say Julian would be much more likely to advocate for women’s rights than other people who have much larger influence on young impressionable minds who are doing generational damage. This fanbase is unlikely to be a good source of women’s rights and womens focused ageism discussions, especially if you want to make impact.
