No, sorry but NO!
Tell me WHY i want to turn scripting on for your page, give me a reason why i should do this after i did come to your page via StumbleUpon, Reddit, …
Tell me why i should not just close the browser-tab and click on the next link?
At least give me one small teaser why YOUR page is so great why i want to look at it.
Otherwise i am gone and will never come back, but if you do, i might come back again and agan and again.
But do not be sad, you are not the only one losing visitors ;)
