I am sorryyou had that experience. I will try to look out for you...and even if i disagree, will respect your opinion.If this is the person I think it is, then I stopped posting on the board for a few years as they'd made it a less enjoyable place to be. My opinion, whatever it was, would undoubtedly be wrong and theirs would be right.
The problem with this hypotheiticl person is that he has a lot of great information and insight.... he just seems to ignore that others may have the same, and more importantly, that he can be wrong and OTHERS can be right. ALso , the wayhe communicates sometimes makes him at least SEEM like he looks down on others.
I have the same problem on other social media with a guy who lives in neighborhood of CHatham in Chicago. He greww up in the neighborhood, and is a wealth of informaiton. BUt then there are times where he acts like the gatekeeper/sole source of info, and looks down on people who don't know, or more importantly, disagree, especially those who can prove he is wrong (even on some level).
