Pretty much, and the rep comments themselves are usually ironically facile....
In regards to the OP I'm afraid I have a rule of thumb where I only use the rep system for pos reps, though I've no issue with you or those who utilize it for the other, especially in regards to the likes of SD....
:e4e:
Without exception I have thought it was funny when I received a neg rep.
When I was still pretty new here I gave out a few negs, I'd bet the total number would be 5 to 7-ish? max.
I only give "good" rep now, to deliver a quick comment or thumbs-up.
I get the sentiment, but I'll skip the rep war.
(edit: so, Im basically agreeing with you AB, incase youre wondering why I quoted you. lol)
