Hi, so I'm going to try to write a response to your points as respectfully as possible. I cannot speak for anyone other than myself but, when many posters comment that they find the perspective of another white male jedi boring, they are not saying that being a white male is bad. What I believe many are trying to communicate is that we have seen that perspective often. It has been the default perspective of the vast majority of Star Wars fiction ranging from the books to the games, to the comics. A change in gender, or race, or species, might seem superficial but it can do a lot to provide new context to the protagonist.
You are right that the movies have begun to feature more minorities and women in leading roles, and most are happy about that I think. Games however, have often been locked into a fairly limited perspective. More than any medium Video Games invite the player to identify and inhabit the perspective of the main character, because you control them. To some, it would be empowering to be able to play a perspective other than what is so often the default.
The Video game medium is going through some changes these past few years. They are seeking to appeal to larger and larger audiences, and part of that is trying to become more inclusive to other genders/sexualities/and ethnicities. People feel the urge to speak up now because the lines of communication with developers is more open then it has ever been. I can understand that you don't want to think about these issues, and that it might take some of the fun out of gaming to know that what you enjoy is maybe disappointing or even hurtful to another person, but that is no reason to insult or diminish them. Most people here are not trying to be hurtful, rather they are trying to express why representation matters to them.
