First I don't know you, while I have encountered BCLG before and second he said that he has seen people doing it providing a specific argument. All you said is that if we don't put this rule it is like sticking our head in the sand, which did not make much sense to me.
If you had said that I have played in alot of pitbosses competitivelly and that I have seen people braking the rules on purpose then I would not have doughted that.
You have to understand that these are open forums for thousands of people, if you do not state your experience and why you think something on the subject then why would you be taken seriously from someone that does not know you?
I have seen alot of people posting opinions on subjects that it proved they had not much experience on...and in open forums it is a easy to lose track of who knows what they are talking about and what not...so turning down arguments is a way of actually seing if the person has any real back up on what they are saying.
So on subjects that I feel are important for this game to be more fun at the end...I express my opinion and I express is abit "authoritative" as it was mentioned. But I do have the arguments and the experience to open a discussion and I don't get offended if someone rejects what I say....I do point the obvious though that is so often missed, some do not like that...and by all means I do like the obvious to be pointed back at me...sharpness I like, indifferent "politeness" I don't
