Why do *most* teen girls have the same damn personality

This is a statement i used to get so angry on hearing, it's such a generalisation isn't it? But i swear i feel like i'm slowly understanding, and before people think i'm a pick me or some shit 😭🙏please let me rest my case first

When i say the same personality i mean like being obsessed with some random pop stars/ or some influencer who sell this image of perfection yet they're a deeply flawed person or in most cases a horrible person, gossipping and back-bitching about literally everyone ( don't get me wrong EVERYONE guys and girls gossip but i swear i've seen so many girls doing that 24/7), and even more than that having the same damn vocabulary and opinions that lack any depth (this one bothers me the most), constantly getting invovled in drama, lacking any passion in their life,and not putting much thought into their future.

Don't get me wrong some of the most passionate people i've met are girls and we've been friends for like over 4 years now, but now that I've transferred to a much bigger institute where literally thousands of people are there this is the exact damn personality of every single girl i talk, and while there is nothing inherently wrong with this personality but does everyone need to have the same damn personality 😭🙏 there is no individuality or passion in most people, and i'm not saying that guys are any better but in my personal experience guys definitely seem to be more serious about their future and passionate people, not all guys are, but the people who are, are majorily guys. For example recently it was nighttime and i was looking at the sky so i just commented that the constellations look so clear and beautiful tonight, it was me simply admiring the night sky yet the girls that were with me (we talk but aren't really at all close, we're just in the same van) kept making fun of me for it and i dont mind it i'm used to it very much so but such incidents have happened so many times and always around the shallow personality girls, they never talk about yk anything worthwhile it's always my relative did that, my beStIe betrayed me, this dude on insta messaged me this, this teacher sucks etc etc and sometimes these conversations are fine but always i mean come on😭🙏 what kind of friendship is it , if these are your only conversations And the most suprising part is i live in a tier 1 city where i would expect most teens to know the value of individuality but this still seems to be the case

Also i would like to say this and i realise this comes off as insanely misogynistic and this very well might just be my personal experience and not the reality but it's just my observation as someone who yk never quite "fit in" (nOt lIkE thE oThEr GiRlS ahh post ik😔🤚🏻) ever since like 3rd grade i swear and now more than ever
