kpop stans are kind of annoying me these days ngl

There are a lot of good things about Kpop sure. But! I feel like kpop stans have placed these insanely high standards on the idols. First, they have to dance well and have flashy choreography but they also have to be really stable or else they're a bad singer??? what??? I feel like these people haven't taken a moment to run in place and sing at the same time. If you do, you'll naturally sound breathy and your voice will be all over the place. So why do these people expect idols to do all of these things while also having something called 'stage presence' maybe I'm too old for this but what do you mean stage presence??? anyway would love to hear why exactly all of these things have to be done by idols
