I have no doubt that Disney will include gay relationships moving forward. However, I think they will stick with gay ones. Man on man or woman on woman. That could be what they consider a healthy safe zone. I don't have a problem with this. Gotta walk before ya run!
What I DO have a problem with is when they announce it and make a big deal about it. When they decided to have one of the Eternals be gay, they announced it and made it a large part of the Eternals news. I hate this. A gay couple should just appear like any straight couple would. Ugh.
