Knowing about feminism doesn't make you a feminist.
All women are different and have different engagements with feminism.
It's not the only feature we have.
It's not the only thing we are.
It's always worth imagining yourself into a position where someone might treat you the way you treat others: it's really as simple as that.
If the way you behave doesn't match the things you say, you'll get caught out.
