For instance, on "sex work", FiLiA favours the Nordic Model, where the punters are criminalised and prostituted women are offered support to help their exit from this abusive industry.
You generally will not find conservatives arguing for that.
Similarly for "trans", the motivation is to prevent the erasure of much-needed single-sex spaces, services and other provisions for women and girls.
Compare to conservatives who look at it mostly from the angle of men should be masculine and women should be feminine. Obviously not something that organisations like FiLiA would agree with, at all.
Your characterisation is way off the mark. FiLiA is an organisation run by left-wing feminists and their conferences cover a wide range of issues affecting women and girls.
