I really can see it both ways. You were offended over a pseudo-religion in a science-fiction setting, dreamed up by some kid from southern California that was highly motivated to be a bigtime movie director...get a grip, dude.
On the other hand, L. Ron Hubbard wrote a fucking book and launched a religion over it...
As far as the 'Tesco' place goes, why the big fuss over a hood in the first place?
They weren't listening to me and were rude. They had three people around me. It was intimidating
So what? What are they going to do, kick his ass? Then he's got them on assault charges. They're store security and management...just how intimidating can they be?
And if you want to quote canon, who's to say they're from the Jedi temple? There were many variant sects among the Force-sensitive...we're splitting hairs here.
