This is what you wrote above:
"Motorized vehicles cannot be brought into the facility" pretty definitive, especially since the facility is the whole convention center.
Definitive meaning 'done, conclusion reached' (which is the definition of the word), the partial quote you gave is, in fact, not definitive, any more so than saying "It's illegal to drive in the USA" is a definitive statement of the law that requires government permission to drive. That statement is an incomplete and potentially misleading interpretation of the law. That's what I meant by saying you misquoted. If I say "Donald Trump is not evil" and you quote me and leave out the 'not', you have misquoted me. Leaving out an important part of someone's statement is a misquote.
In contrast, here's what I wrote:
So the rule above doesn't say you can't bring a hoverboard. The interp of the rule above seems overly conservative. Someone could easily ask the Con center management for permission. I don't know what their standards are, but it does talk about facility management approval being theoretically possible.
First sentence: true. Third sentence: true. Fourth sentence: true.
The only thing I wrote there that is not blatantly true is the second sentence, my opinion that this interpretation: "Yeah, no hoverboards." is overly conservative.
And I stand by the opinion. Saying essentially "hoverboards are not allowed" and implying "at all" is overly conservative, as hoverboards may in fact be allowed on individual merit. And indeed, I stand by that opinion that it is not a definitive interpretation of the rule, even if you do happen to know some of their lawyers. Their own rule leaves open the possibility of allowed hoverboards. So to say "hoverboards are not allowed" is the definitive interpretation of the rule is as incorrect as saying "you can smoke anywhere you want in the United States" and leaving out "where it is permitted".
I guess you could try to argue about the definition of 'definitive'. I'm just going by a combo of the dictionary and common usage. And I'm not interested in debating that definition. I think what I've said here is both all I want to say and all I need to say to defend my position. Not trying to be a jerk, sorry if I came across that way. My initial point in all of this was that I didn't want people to neglect the very real fact that they can ask the convention center staff for permission to bring a hoverboard if they choose to. Someone reading "no hoverboards" might not have realized that.
Peace.
(I'll add that I'm not saying Marimacc was out of line in any way. Her being a rep of Gen Con, I think it's pretty reasonable of her to take the conservative position when she gives what will be taken as an 'official Gen Con position'. Better for her employer to be seen as saying "no" than to be seen as giving permission.)
