I definitely do not think you are a complainer. I do think you tend to post negatively but I don't mean that in a bad way. There are people on here that are basically trolls and you are not that. I just think you have a glass half empty perspective and you post from that perspective which is fine. I think your positions are, at a minimum, reasonable and well thought out.
I do agree with Brock in that the repeated beating of dead horses on some subjects is tired and I think the folks that post from the glass half full perspective need to be allowed to do that without being lectured about how foolish that perspective is. Just my two cents.
