The lengths Lucas apologists will go to...the quotes I provided from Lucas's speech to Congress were dismissed as not applying to him or his films

Maddening for sure, but easier to take when you realize they're doing it out of insecurity and fear of not being right. A point you nailed perfectly with this comment;

I just find it so amusing how threatened apologists are just because we don't share their opinion, and how they feel compelled to try to shut anyone down...

In our culture of yelling down your opponent e.g. any political radio or TV talk show, the internet provides everyone with the loudest voice. They're safe and correct (and arrogant) behind their keyboard. If we were all in a room together, the conversations would be very different.

Also, a great many of those apologists are too young to understand loss. Every film they love is essentially the same as it was the first time they went to the theater to see it. A tweak or two by the time it's released on DVD isn't an issue because it's still now - not unlike the title crawl change for my generation. Thirty years from now, when they still can't get the theatrical versions of Dark Knight or Avatar, they'll understand.
