What would that prove??? If you have something to say that does not fit your approval just print it out. The like button was added basically to prevent the +1 answers which are annoying as heck. Maybe you want to start a trend and use -1
Very few postings I dislike. This site is quite liberal with posts and I think that is good. I'm not a confrontational individual. I like to live and let live. What I disagree with or what I dislike I ignore. It's all good.
