There are those types of people on every public forum, but I have to say, RV.Net is one of the best places that I frequent. I post periodically on IRV2. I try to only post about those things I truly know about, since I want to make a contribution. On IRV2 there are folks that will attack people that are posting factual information. People that know what they are talking about. As a result I rarely frequent IRV2.
If you spend time on this site, you'll get to know those that know what they are talking about. But attacks on people are much less then on other sites.
