The present voting system vis a vis "super delegates" does not appear to be in any way democratic?

Once again, "super delegates" are a feature of the Democratic Party only. The Republican Party doesn't have them. The Libertarian Party doesn't have them. The Green Party doesn't have them. Political parties don't have to be 100% democratic, only as democratic as their membership chooses to be. They are private organizations, not government entities. They can adopt whatever rules they want. If the Democrats want to choose their nominee by holding a séance in the middle of the Mojave Desert, they can do so.

Having said that, super delegates are really a bit of a red herring anyway. Once a candidate accrues a majority of regular pledged delegates, almost all the super delegates who may have been supporting another candidate change their support. It happened in 2008. As soon as Obama won a majority of pledged delegates, all the Clinton super delegates changed their votes.
