DU has standards for joining and posts that break the agreed-to contract may be hidden by jury. Serious offenders get tombstoned. Outside of this, people respond to our posts when and how they like.
I made a snarky remark to your post because I'm still drinking coffee and not particularly interested in having a lengthy discussion at the moment. Further, I disagree with you that "Obama just doesn't know how to compromise," which I thought, at first glance, was a ridiculous claim and a bullshit right-wing talking point. So, my initial reaction was disrespectful and without much regard to peoples' feelings about their self-images. It was also an honest claim; when I saw your subject line, that is precisely what I initially thought.
Anyway, again, I'm sorry if I hurt yours or anyone else's feelings with my apparent fat joke. I should have just "bullshit."
