Where to start? You give us so much to work with that it's really not fair at all.
First, have you ever heard the line "in Order to form a more perfect Union"? As the OP said, reread it if you haven't because even the founders knew that they'd never achieve perfection (hence the word "more", indicating that they're not there yet, and never will be). All that they, and subsequent generations, could do is try to get closer and closer to perfection.
I've never heard anyone, to include the OP, claim that the constitution is perfect. You're the only one's that come up with that line.
My proof? Have you ever heard of something called "The Bill of Rights" and the subsequent amendments? If our founding fathers would have thought that the constitution was perfect why would they have instuted the ability to change it?
If you want to "overhaul" the constitution, you do it via amendments. If you feel so strongly about it you're going to have to do something more substantial with your life than trolling IMGFLIP.
