I don't really see what your problem is with me. Do I give a "thumbs down" to a post I don't agree with? Absolutely. That's what they are there for, right?
I wouldn't call that complaining, I'd call that disagreeing. Is that not allowed on CB?
If you look at my profile, you'll see that I give way more "thumbs up" than I do "thumbs down." I also give lots of smiley faces, cause I'm a pretty happy guy!!
