How can i convince my parents into letting me go to a rave?

I know that i would live raves and as soon as i turn 18 im going to be going to them all the time so to me theres no difference if i start going rite now being 16....i love the music the dancing the light shows and all the pretty lights..i know its my place to be but they just see it as a drug scene but to me i dnt care becuz ppl there are nice and friendly even though there probably on ecstasy or something...drugs are everywhere not just at raves so i dnt see the big deal and besides i already take ecstasy (i know its bad) so wuts the difference if i take it at a rave..
