If your feelings are hurt because people feel your film sequel to your own or someone else's film was a letdown or that your character was annoying you shouldn't make films.
Then good luck with seeing any new films anytime soon, because lo and behold, they are made by human beings who have feelings.
We aren't talking here about constructive criticism, we are talking about the ridiculous level of personal attacks and abuse that have been heaped on these people, including here in these very forums.
Lucas doesn't seem depressed or as if he had been abused
Based on what exactly?
If you honestly can look at his behaviour, his interviews and his decisions since the prequels and
not see someone who at least partially just gave up and retreated behind the scenes I don't know what to tell you.
Personal attacks on the people shouldn't be considered acceptable, strong attacks on the work shouldn't be considered to be personal at all, let alone abuse or harassment. I don't believe people complaining about Lucas's work was heaping abuse on him.
Have you seen the youtube videos, the blogs, the reports of him being stalked, the break in, the hyperbolic personal criticism personified by the phrase "George Lucas raped my childhood"?
If that's not abuse I'm not sure what is. Does he need to be tied down and tortured before it qualifies?
I'm always amazed at how personal people in forums (including here) become with Gene Roddenberry. It's not much different than people criticising Lucas or Kennedy for their impact on Star Wars. It's like most of us love Star Trek but mention Roddenberry or Berman and out come the barbs which usually are not about the show but the actual people.
In some cases I would tend to agree, but much of the criticism of them is much more low key and much more justified. If there were an equivalence between the two scenarios I'd say you were right, but I'm not sure there is. Lucas and Kennedy are accused of making bad films and publicly torn to shreds in a very personal and sustained way, Roddenberry and Berman are accused (with plenty of evidence) of being sexual predators whilst making good TV shows. The barbs are about the people precisely because the issue is with the people and their behaviour, not with their creative output.
You yourself have repeatedly publicly mocked and insulted an actress for no reason other than her waistline, I assume you've considered your own actions here?

Moral Equivalency on display.
Not even remotely, what a strange thing to say.
