I've been a member of several other forums, most of which I've left because the political divisions became so defined that certain members shunned others who did not share their beliefs. The proponents of a political forum state that the hostilities will remain in said forum, but from my experiences, this has almost never been the case. Schisms carry over into the other forums and can permanently divide a forum.
That being said, I know that I have little say as to whether a "politics" forum is actually created, but I fear that it will be used primarily to vent. I'm interested in learning about aviation and developing good "forum" relationships with other aviators, and I don't want conflicting political views to come in the way of that. Needless to say, if a politics forum is established, I won't post in it.
