Pax, again, your communication queue's is at odds with 99+% of the rest of the world. You need to accept that in common communication, what you wrote, or even more so if you would have said it, would have been construed as others have taken it.
You need to accept that you dont pick up on sarcasm (very well) or innuendo. Where you said what, was what the vast majority of the world would have taken as implying it was not allowed in a normal 40k game. It was said at a time that a contrarian view would be expected, so when said it, it as taken as such. Couple that with the previous FW rulings that the 40k approved stamp was needed, you only get a further re-enforcement of said interpretation.
Again, you need to accept that it is you that is not picking up on the verbal implications that you are giving off (un-knowingly or un-wittingly).
In this world, intention is a large part of communication. It is not just about what is written, but about the inflection, intent, innuendo, etc (add in any other "in" word).
Example. "take my wife please"....look it up on the internet. famous comedy (albeit hack) routine.....the comedian didnt' what you to take his wife...it was the joe that matters....everything is not literal.
Sometimes it would be better and probably less frustrating for you to just say "sorry, not my intent", then trying to prove your point. Again, not trying to be an ass, just pointing out that it is your way of viewing the world that is at odds with the vast majority of the rest of said world.
