There must be NO flags or downvotes. If you want to live in peace you need no spears. If you give people spears - they will poke each other "in a name of greater good". And than a flag war begins.
For what?
If you don't like something - just ignore it. If no one can hurt you, you need no means to hurt others yourself.

Flags must be abandoned. You can do so much more if there is no violence in system is possible by design.
