I didn't go because: sexuality

I'll take the bait. You created this whole "What percentage" scenario yourself. No one was saying those in a minority don't deserve recognition (although why it's necessary in the first place is a better question). The complaint is how that recognition is being forced into a story and onto a pre-existing character that had already shown his sexual interests (Attempting to romance Princess Leia). And why it's necessary to the story.

Bowing to minorities and taking characters that had existing traits and changing them to suit a small minority of people is no different than taking a character who is a minority race and making them white. Why is it not ok one way but fine the other?

I haven't seen the film, I do not know the context of the scene. But it's obvious how this has become prevalent in modern film and TV and I do find it funny how every group, even majorities, now have to be represented in nearly everything released for public consumption. And not only how unrealistic that expectation is but how absurd it is to expect over 50% of our cinema to cater to less than 3% of the population.

Entertainment was much more entertaining when it was tactful and subjects of this nature were left mostly to the viewers interpretation/imagination and the story was the most important part of the film. Now movies get reviewed and panned for not being inclusive enough regardless of how bad or great they are. It's bad enough the majority of movies now suffer from writing with the mentality of 12 year olds and the elegance once shown on screen is now just a brainless expose of "This will be cool, who cares if it makes any sense".

Now add the lack of escapism that was once possible; The desire to immerse yourself into another world to get a break from the real world. Which now is nearly impossible when almost every movie must contain a social and/or political commentary. Otherwise people from all sides complain that you haven't taken a side so deserve to be vilified.
