Change "I am your father" into "Obi-Wan killed your father" as shot originally. Discard everything after that scene, including of course the prequels and sequels (but keep Rogue One and Andor because this is now for grownups). Rewrite and reshoot everything else based on the premise that Vader and Anakin are two separate people, as was originally intended. Make a prequel about the relationship between Anakin, Vader, and Obi-Wan, in which Vader‘s face is that of David Prowse. And establish Darth as his first name ffs, not some stupid title or degree or what.
No, just like you don’t learn to drive, program, play an instrument, speak a foreign language, self-defend, etc. that way. The practise phase isn’t optional.
There may be people who consider it a slur but there are also three species of butterflies, two species of mammals, and a few dozen Wikipedia-worthy people with that name. I mean, I’m all against insulting people, but come on.
Yes, because the definition of normal is "within this many standard deviations from the average", and people consider themselves average until learning otherwise.
