Hmmmm...
"When you do find it necessary directly condemn a group or idea make it clear what and why you denounce them. If people mistakenly think they are part of the group being attacked they will vote you down. Be very specific."
There is a thin line between narrowing your target of condemnation, and conjuring up some 'phantom enemy' to make your point without attacking anyone.
E.g. "I can't stand these 'right-to-bear-arms' freaks! Not the ones who are satisfied with handguns and things - they're okay. But the ones who insist on their right to bear grenade launchers and machine guns!"
This is obviously a way to rant while only opposing a tiny group of people. (In fact, this is probably a good way to slip in a bunch of writeups without attracting downvotes... hmmm...) 8^)
The problem lies in the fact that you are not saying anything; you are not expressing any useful political or moral opinion. If you're going to say something, at least have the guts to make your stance clear and your attacks wide-ranging.
