We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Of course Solo shot first. On the other hand, the point about Greedo shooting first and missing by a mile is consistent with Star Wars Canon as Greedo was something of a putz as a bounty hunter and had previously failed twice to get Jabba's money or bring in Solo. Whittle makes a good point here, but he kind of cheats on the reason Lucas changed the scene digitally. Lucas was heavily invested in the whole John Campbell view of myth and myth making - Solo shooting first didn't not fit the general shape and perception of how a hero should act, so the scene was changed to reflect that.
With respect to Indiana Jones and the infamous sword fight, well it wasn't quite the way Whittle portrays it. In the original script, Jones was challenged to a duel by the Cairo Swordsman and the fight was intended to last for a while with Jones using his famous whip against the swordsman. As it happened, Ford was suffering from dysentery and could keep a clean pair of pants on for more than a few minutes. Ford suggested they "just shoot the f***er". Steven Spielberg agreed resulting in the biggest laugh of the film and one of its most memorable sequences.
I realize that we can make much of almost anything by way of allegory, but Whittle's points (not necessarily bad ones, just a little twisted to make his point) here are stretched about as far as they can go without breaking.
