Paul, my statement was not meant as an accusation, but you have just admitted yourself that you will happily censor someone's post if it doesn't agree with your views. And you are completely within your rights to do so. My point is that if you have a political forum, then it should be a balanced platform where even people that you don't agree with can state their view in a respectful manner. Yes, certainly remove any disrespect and malice, but accept that there will be posts that don't conform to your way of thinking.
Imagine the governor of Montana joined Permies. Now he probably doesn't know much about the other areas of permaculture, but he's probably has a fair idea about politics and the effects on the other areas. Now according to your rule, he can't post in the politics forum because he hasn't yet earned enough apples, and it will probably take him a fair while to get them seeing as he doesn't know anything about green roofs or keeping goats.
Then at the same time a farmer from Virginia joins and he too has to earn his apples. Are you going to treat them both the same or are you going to try and get the governor his apples so he can make a useful contribution in the forum? The farmer might take exception to that. BTW, his name was Joel, and he too probably has a few good ideas.
There is an old adage concerning British pubs. If you don't want to get into a fight, don't talk about soccer, religion or politics. Maybe that should be the way with internet forums as well. Or maybe, everyone can
have the chance to contribute something as long as it is in a respectful manner.
