I mean the roles that are seen as normal/gods will/decent/natural - and if people do not act 'naturally' as per the ideas of such authorities, all kinds of pressure is applied, according to the laws and habits of said society.
If you are gay, and people want to make you straight, if you do not conform to gender roles, if you want to live in another way etc great presssure is brought on to 'cram' you into the (usually) quite small box labelled 'gods will' or 'natural'.
