I'll ask again.
How did the Beatles advocate self harm and body mutilation in women and girls? How did they promote the idea of girls as unthinking airheads?
How did they encourage a generation to hate their own bodies?
I'm a media /history graduate, and technology change does change society and there is generational shift and clashes. It's observable.
But saying this is comparable to the Beatles in terms of a generation is wrong. It's the wrong comparison. It's not about rebellion in the way you think. For that look more to climate change. Spontaneous, grass roots driven and not commercialised (though becoming commercialised).
The era of the Beatles wasn't manufactured. It become commercially successful but it wasn't cynically created in a boardroom like this. Beatles clones were, but not the Beatles themselves. This movement is more about feeding on the growing sense of isolation and community breakdown elsewhere in society. It's driven from above. Community only exists online for many now. In an unreality. It is the rise of the unreality.
And it's not rebellion. It's conformity driven. Don't dare to be different from your peers. Fit in at all costs. It's the fear of not ticking the right boxes for gender which is stronger than parental influence. It's not breaking away though. It's reinforcing old tropes that parents and grandparents recognise. It's not fresh nor new. Gender bending is so 1970s afterall...
For a better comparison you want to look squarely at fashion and advertising for this reason. It might be comparable to Twiggy encouraging young girls to be ultra thin though, in a way that's unachievable for their bodies. And this trend of hyper promotion of the unreal and unachievable has merely accelerated and become more pervasive as commercialism has increased. That's not a cultural shift, that's more marketing and more misgyonist push on the same concept of tapping into beauty ideals to make money at the expense of female socialisation which is built on a lack of self worth and confidence.
And this isn't a vision from women for women. It's still through males eyes and male desire. Even if the Mulvaney bud light campaign was run by a woman. (A woman who incidentally looks to have lost her career for fucking it up)
That's why the feminist argument still holds true on it.
And even if you do compare it to the Beatles, what you are in effect saying is that is a trend which is time limited and will crash and burn when the next thing comes along. It's got a level of superficially to it rather than profound social change like the civil rights revolution. Civil rights needed intergenerational support and value and it won social consensus with a sufficient spread of society rather than singular demographics.
It's bullshit. And it will come crashing down.
