You can not have your cake and eat it too?

The correct expression is: "You can't eat your cake and have it too". Think about it, America ... the only way you can eat your cake is if and when you have it! Once you have already eaten your cake, you can't have it any longer. Hence, you can't eat your cake and still have it! Please stop butchering the English language. Stop making mainstream what the lower classes ignorantly misstate.

I realize this is a long road, but I'm on a mission to make Americans say things the right way and not merely capitulate to ignorant folk saying things the wrong way!
