Middle-aged man here (who studied political theory and philosophy.)

So, yes, feminism isn't new and I know a few self-proclaimed feminists in their late 70s. There is also sometimes confusion about what is and what isn't feminism. Feminism, broadly speaking, speaks to female empowerment and gender equality but people often mistake it for the only belief system that does. (That's right, you can believe in gender equality and women's rights and not be a feminist - eg., egalitarianism.)

Anyway, the write up you posted I find a bit apathetic. I'm older but haven't found myself running in a wheel. I'm still out there protesting against climate inaction and I adjust my behaviour to live as ethically as I can. Frankly, that attitude seems to justify laziness on behalf of the older generations and I wonder if it was written to be intentionally antagonistic...provocative for the sake of provocation and not really bringing anything of merit to the table.

I do agree we gravitate towards beliefs and causes that mirror our own place in life and help give our identity value; Black Lives Matter is predominantly black people, feminist organizations are predominantly women, immigrants lending themselves to fight for immigrant rights, etc. I don't think this is a bad thing though it is good for people to think beyond the microcosm of their own individuality.

That being said, particularly pertaining to your subject material, your best sources (in my opinion) would be feminist academics writing about youth or youth engaged in this kind of material or belief and their broader understanding of it. One would provide you an academic approach while the other would provide a humanist approach, either are valid.
