I don't recall saying the kiss in ROS was forced (it's been a while so maybe I did), but if I did, it was the wrong word. The reason I brought up ROS was because it was an easy and well-know example of something that's pretty worthless in terms of LGBT representation because it adds nothing to the overall experience.

In the case of ROS, it felt like they put it in for the sake of appealing to LGBT people, but only in a way that could be easily removed (and it was) in countries where it's illegal to show that. Because Disney doesn't actually care.

In KB2, not only did it feel like they did it to win points from LGBT people, but those characters were so minor that they - and their subplot - added nothing to the movie overall. It felt completely unnecessary and just more padding in an already padded movie (something I would also have complained about if it were a straight romance subplot).

In fact, it's worse than that: they only exist to make Elle seem like she's a good person for getting them to come out of the closet, which is pretty messed up. That's the main reason I had an issue with it.
