"no opposing arguments are allowed here no matter how good they are". In my experience that's not correct. I haven't been commenting much lately, and when I do it's often because I disagree with something, and thus have an opposing argument. I've never received any significant downvotes, though I have received my fair share of counterarguments, most of them intelligent and all of them in a civil tone. Interestingly my average karma per post has never been higher.
