BTS are the first Korean band to headline Wembley Stadium.

I definitely understand your point of view though (even though I might get downvoted too, but still). This happens for a lot of groups, and I see it happening with some of my friends too. One (or several) bad moments and experiences throws off a lot. This is why I stick to my small group and try not to venture too deep into stan twitter or other social medias within the fandom.
I would definitely recommend just subscribing to their official channels and just those to keep updated if you would like to, just for the sake of being able to keep up with their mountain of content.
With that being said, I also am glad they continue to outdo themselves! Their stages continue to stay amazing and I'm very happy they livestreamed it so that others can view it all over the world, even though I personally wasn't able to watch it live.
