As someone who lives in Japan, that is true as long as you stay inside the tourist bubble. Once you start venturing into places not meant for visitors, the difficulty goes from 0 to 100 real quick. That said, sometimes those experiences of struggling communication can be among the best you’ll have here.
the fact that the camera crew seemed to like focusing on them being intimate makes my brain say, “this must be important to 23rd century humans in some way”.
Might I also suggest that another possibility is that until very recently, there has been so little gay representation on TV that merely depicting it at all, as Discovery has done, can feel jarring to some.
A friend of mine was complaining about the same thing back on Season 1, but I asked him if it had been a hetero couple shown brushing their teeth together or having a smooch would he have minded and he admitted probably not. We chalked it up to just not being used to seeing that with a gay couple on tv.
