Why my family is against my marriage?

fear. fear of being seen by others, by the community. seen as cooperating with something which is not accepted by the community. (at least in the perception of your parents, even if it's not true at all actually) because if community rejects you, you are in danger, you are alone, and survival is very hard then. it all boils down to fear of death really. survival. acceptance by the tribe. this is actually the first tool of manipulation, by society or family "you will be left alone, billy, if you continue this unacceptable behavior!" not much you can do about it, really because it's their choice, what they choose to do. to give into fear, or to do the right thing. and the right thing is always to let the individual choose. if you choose him, and he chooses you (supposing you are a she :D) then, that's it. as i see it, society must follow the children, not viceversa. because children are WAAAAY more updated, more adapted for the future, more in tune with what universe wants next, more in tune with what society wants next. but, yeah, "what? how can you say parents must follow children???!!!! it's my child!! He must do what I say!! " :D You know the drill
