I'm a member of several other forums and one tractor oriented forum in particular allowed politics to be discussed in a seperate area. As stated above, the anger, and ill will spilled over in the rest of the forum. That forum recently went "poof" and many of it's moderators built a new forum to take it's place. One of the first things discussed during the creation phase, was whether or not to include the politics section. It was almost universal to decide "No way!" If folks want to discuss that kinf of stuff, there are literally hundreds of sites on the web to do it. Why add it to a tractor site? It really became a major problem at places I've seen it allowed. And it certainly did nothing to add new members, just caused many folks to leave with hurt feelings, or in disgust, neither good for a site's well being.
As to the proper way to install toilet paper, my wife is SO HAPPY if I remember to do it, she dosen't care which way it rolls, although my cat will unroll one installed over the top, so it tends to be installed under the bottom.
