I don't see how forcing people to click a red/green button is going to change anything.  People aren't reading the forced voting, they are just clicking. So it totally defeats what you are trying to do.  They just want to get back to where they were, not 7 clicks later. ridiculously and needlessly annoying. Just an absurd philosophy that can't possibly work, only provide false commenting data. 

This is a simple case of GIGO. It comes at the expense of annoying the people that drive the comments.

P.S. Not even letting reader know what comments are new since the screen was last active is such a fundamental necessity, it only shines light on how poorly this commenting tool is designed.  Take note from Disqus. People want their data aggregated, searchable, and convenient. People don't have time to go through repeated attempts at finding comment content and responses.
