Should all idols be expected to have talents to sing "live" as singers?

Even idols are singers. Basically, they have to sing live.

Or idols are all visuals. A song can be replaced with lip sync but it doesn't have to be entirely that. 

1. [+260, -5] It's all about skills. We can tell they're lip syncing just by looking at their faces. This is what K-pop is now. 
2. [+246, -1] If you can't sing, don't go on stage holding a mic!!
3. [+207, -64] Lee Soo-man who claimed lip sync was also a genre and got cursed at made a mess of everything. Look at the squirrels claiming AR is live ㅋㅋㅋ, you need to get sent to the mental hospital along with Min Hee-jin.
4. [+195, -1] Of course, you must have basic skills.
5. [+191, -10] What's the point of trying to suck out juice from a stone that is ugly and can't sing on top of that? So many tone-deaf maids here... f*ck
6. [+101, -1] No one asking idols to have the same talents like singers. But at least have the talents to sing your parts properly even if it's for a few seconds. If you can't sing while sitting still become a dance idol, don't come out as a singer.
7. [+93, -82] More than just singing, they should learn how to do basic choreo.. 
   
8. [+70, -35] I'm honestly curious what would happen if BTS Jimin and Jang Won-young were ordered to do a duet together ㅋㅋㅋㅋㅋㅋㅋ
9. [+68, -11] TWICE Momo, Kang Daniel, Jang Won-young.. just to name a few, there are more besides that. Whenever I watch their stages I just.. I'm trying not to call them out but I'm seriously in shock.. aren't they embarrassed?
