Paul, with all due respect I think there has been a great deal of confusion and over reaction here.
I don't think anyone is suggesting getting out a slide rule and making sure everyone's kit is as screen accurate as deemed necessary by a consensus, or secret committee etc.
What "I" believe this is about is how to deal with someone who "wants" to march with us, but who's apperance is so far removed from being remotely recognizably associated with the Alien series, as it would be confusing (and possibly embarrassing) for people observing our group during the parade.
And I'm talking the most extreme end of the spectrum- like camo shorts and body paint, or "joke" cardboard armour like the afore mentioned "Cardboard box Stormtroopers" who marched ahead of the 501st.
But just to be clear- if someone made their armour out of cardboard (or paper mache, or rubber bands) yet put forth their best effort to make it look as it appears in the film, I would be okay with pretty much any level of uniform.
We all started somewhere.
What "I" want to prevent is someone coming along with literaly "no" costume, OR a costume designed with nothing but contempt in mind---
By "contempt" I mean a costume (or blatant lack there of) that is controversial enough to immediately illicit feelings of distain or disgust for the sole purpose of seeing that kind of reaction from the crowd or fellow costumers.
I mean those here who are so vehemently opposed to "any" standards aren't suggesting that we should always have an unswerving "anything goes" open door policy for the parade right? Otherwise I should be able to wear my Admiral Kirk uniform during the parade.
But that would make no sense whatsoever right? Well that's partly my point- we can't just have this "whatever makes you happy" line of thinking as it is "another" slippery slope of just how extreme/controversial or done-in-bad-taste (or has absolutely nothing to do with the Alien series) a costume can be before someone finally says umm, no sorry we really can't allow this to be associated with our group.
However I also believe that none of us around here are going to wear something crazy enough to be "banned" from the D-Con Parade... Unless it was for no other reason than to be in direct protest to the suggestion of having some limits as to what is acceptable.
