I take exception to the 1/2 policing bit. This BB would be like all others without it.... I'm not aware of anything that has been deleted re Israel. Your comments are 100% correct re opinions and should not be edited /deleted. One's personal opinion should be respected by all, no matter how strongly someone else feels about it. After all, it's feelings and opinions that makes up one's character.
If you feel there have been threads unjustly /unreasonably deleted, then perhaps you should complain, or object, to the Moderators. I am certainly not aware of any threads that have been subject to this, but there are three other Moderators. Each will have their own opinion as to whether a thread/post is deleted/censored etc. If we get a complaint that is serious/fraudulent/racist/controversial, we do discuss and decide what we think is best and where possible, try to arrive at a unanimous solution. That may not please some, but it's the best we can do.
If you have a specific issue, perhaps you should raise the point formally.
