Couple quick comments from a non-breeder who enjoys learning why I am not a breeder.
In forums, there is always a bandwagon presence. If someone is rude (duly noted that the definition of rude is subjective), then suddenly there are others who chime in simply repeating what has already been said with the same "tone". The same thing happens as BakersDozen points out, when one person cries foul, other lurkers jump to their defense as well.
The other thing I keep in mind is that crying foul works both ways. Just as those being answered may need to have thicker skin and tough it out through the cold hard facts, should those giving the advice also tough it out without becoming defensive when people question the tone of their responses if they don't agree?
Bottom line - Neither the people getting information they don't like nor those giving advice that is questioned need to leave. I wish there was room for all........
