To me no it doesn't piss me off when I receive negative "rep" when it is presented the correct way but when someone uses / abuses the system because they disagree with you for having a difference in opinion is obtuse.

Yes it pisses me off when someone uses a "rep" system to flame some one for an opinion or stating a feeling and it bothers me when someone does it just because they can with out providing reasoning behind it.

I think if someone is being an ass then yes they deserve negative "rep" for being one. this is not just limited to being an ass it also includes being an idiot and what not. I don't think people should be called out for a matter of opinion or for ignorance via a "rep" system. The better way to resolve the issue is to post on it and further create conversation to understand ones point of view on the situation.

Then again I don't think that a positive rep is always justifiable because someone agrees with a part of something that some one posts. Positive rep should be given for well thought out posts that contribute to a conversation.

Also note that I use "rep" as a broad statement because it is not called rep at all forums.

Then again this whole post is a matter of opinion.
