When I read comments, I realize the audience in largely American with a sprinkling of other English speaking territories. I do have to say, culturally, we all should be trying to view media relative to their microcosm.
Pokemon as a whole, is a Japanese product made for and by the Japanese. It does have a worldwide appeal and has been shared with those of us who are not Asian Islanders. Therefore, you need to view the context of the show and the games through the lens of the eyes of the creators and their target audience.
Public displays of affection, whether spoken or physical, are in Japan akin to bygone eras elsewhere. So thus, publically embracing and other forms of skinship are viewed as "intimate acts". Even something like hand holding is given weight in their culture.
Some people might view that all as prude or "sexually repressed", but I do not. When you see characters in their media finally kiss or Advance their relationship, it's given weight and respect; something many people have forgotten in an era of apps like Tinder.
Artistically, narratively, and culturally even an act like a kiss in this context was like a bullet fired; and we're still hearing the echoes from it. It was an incredibly tasteful depiction, using the old adage "Less is more"; which in this case if you watch the reaction of the secondary cast including Pikachu it was way more meaningful than anything they could have just shown.
