Karma

I like the general idea behind the Karma options however i think that it can be used in the wrong way.

For example i seem to always get into a discussion regarding PS3 vs 360 and yes i admit i get annoyed sometime when some people decide the fate of Sony before the ar has even begun but i try not to show this in the posts.
Here is an example of what i mean.

I honestly dont think i am in kind a bad Karma however i have been given a bad Karma marking :(

Do you think this warrants a bad Karma ranking and if so can you explan why you think that as I just dont know how it can be :)
Sorry not sure how to hot link :( if anyone knows how to do it let me know and i will edit it.
