I think it's fine! I equate a lot of K-pop to watching a movie. I love seeing K-pop idols get into the attitude and persona of the character they portray. That's why different concepts exist. They play a different character for each concept. The way they deliver the lines just as actors and actresses do is amazing. Not everyone can do that.
Idols get a lot of flak for being idols instead of artists, but I think their ability to portray and express is an art form.
Most of the disses are just general messages to the haters anyway. I would question it a bit more if they dissed a specific person while using lyrics that weren't written by themselves.
Of course, they get bonus points if they write their own lyrics. That makes it much more interesting, but I can still enjoy without as long as they have the attitude.
