Well IMO -reps just adds to players looking for negative thoughts.
I will use an example:
I post my opinion, but another player doesnt agree with my opinion so he -reps me. Does that make my opinion wrong just because another player doesnt agree with my opinion? No it doesnt, but it does show how we all have different opinions, and that is what makes us unique individuals. But we have a system here that focuses on opinions. And it also adds to players not being their true self cause they worry about being critisized for having an opinion that doesnt go with what society says is cool.
Personally I will never -rep another even if I disagree with their opinion/post. Who am I to say that anothers opinion is wrong? And IMO those who -rep others just cause they dont agree with the post need a reality check. The -reping player is not the supreme being, so where does the -repper get off saying that a player is wrong for having an opinion. So I say that the grepo external posters need to loose the GOD complex on thinking that their opinion about something is the way it is and any who has a different opinion is wrong.
