I suppose it's because I've never seen the SEs and only one of the prequels - but I'm not fighting the war the way some fans are, nor do I have the hatred for Lucas that some fans have. There isn't anything for me to forgive because I'm not familiar with the SEs & prequels. Truth is, for me, Star Wars77 isn't ruined\destroyed\etc. I have a watchable, enjoyable copy of the only film of the six I have any interest in. If a higher quality DVD or Blu-ray is ever released, I'll get it. If not, I'll watch the one I already have.
I do, however, sometimes discuss the SEs & prequels as best I can considering my lack of familiarity, but it's not from a position of anger. It's more of a "Man...dude's jacked up" point of view. As I've said before, I find his obsession with trying to change the past and his constant lying of the fans to be fascinating behavior, in a train wreck sort of way. I can certainly see where it would be frustrating for some. For me - someone who was there in the 70s and experienced Star Wars first hand - I know the truth, so I don't lose any sleep over George trying to tell me I don't.
