I’d argue you were correct - it seems more accurate to me to say that ‘femmes are pressured to worry about their image’ than ‘women…’ as many women unlearn the lesson that they must portray a certain version of themselves, whereas femmes generally conform to it willingly, hence why they’re ‘femme’. Therefore, the women that are excluded by the term ‘femme’ are the same women that don’t fit the criteria of using Pinterest for their self image…
But this nuance with woman/female/femme is one of the more complex aspects of modern conversation. Last decade it was there/their/they’re. FTR: Am transwoman, am femme, felt included :)
