Gracesgran, this is an opinions forum, the clue is in the word opinion
Where does it say that Bridgeit? The only word I can see that GN attaches to forum is "discussion". In a discussion you may agree, disagree, offer evidence for your point of view or deny that there is any supporting evidence to uphold someone else's. What should not happen is that people offer an opinion and expect it to be accepted as fact or that they try and close down a discussion that doesn't support their point of view.
I can really see why we are having issues with young people at university who think "safe spaces" means not having to listen to the other persons opinion. They have obviously picked this up from the older generation where, just as you do with You are interfering with the flow of a thread ... they, and you, attempt to close down opposition to the view on offer. You are also making very personal and derogatory remarks - not the way of a discussion surely?
