Appreciated jersey tom (EDIT:....oops MX tifoso) my sincerest apologies!!
Re the topic:
Why not have a system whereby naysayers can bypass the vote system upon login and carry on as is currently the norm?
By doing so their fears are allayed, but their posts arent privy to those who endorse the vote system.
It may be two tiered, but it allows the user(both voter and non voter), to make up their own mind for each post read.
So you can have your cake and eat it
