I have found the information and help many folks here offer extremely valuable, especially in terms of my decision-making before spending big bucks.On the other hand, I am strongly repelled by those who are unkind, rude, denigrating, or aggressive with their posts. One of my values is civil discourse, and it can be difficult to tolerate the problem folks while I am gaining from the others.
As others have said, this seems to be the nature of anonymous forms.
