there's not really to much to say to them...to me it sounds like they have an underlying problem with it somehow since they call you a loser and shyt i'd say they have some serious issues they need to work on....those are the type that are completely against it for some reason (some past expeirence has probably made them think that) and they don't know what else to say to you except things like "your are a waste of life, you will ammount to nothing and blah blah blah".....i really doubt you will get through their thick skulls ont his one sounds like they have their mind made up they aren't the type to change from what i can read.....all i can say is bear with it and do what you think is the best idea not what you want to do....if you are still under 18 it would be a bad idea to just do what you want because these are the type of parents that will call the cops on you and stuff atleast from what i can read and of course gereralizing parents with the same experiences.....so do what you gotta do to lay low until you move out becasue they still have (to a certain extent) have control over what you do and what happens to you...of course you can make your own decisions and face the consequences but the best would be to show them what they want to see and hide what they don't until you can move out.....if i was you (since i'm a smart ass) i'd show up the day i move out smoking a fat ass blunt and walk in their house and say "now what bitches!!!????" btw if this doesn't make much sense is cuz i'm drunk so drink a half a bottle of tequilla and read it again.....
