Anti-femme culture (and feminists aren’t immune to this) thinks the effort put into femme presentation is a waste of time and energy – or, at the very least, time and energy that could have been spent doing something more important. Anti-femme culture thinks “pretty” probably means “dumb” even when struggling against a culture obsessed with an impossibly narrow beauty standard. Anti-femme culture thinks you can’t do math AND do your nails.
We are humans! We contain multitudes! I do not think it is a problem that teenaged girls are interested in experimenting with presentation via fashion; I think it’s ridiculous and misogynist that they are ONLY encouraged to do that – and that boys don’t have the same freedom of expression.
