And me i find this hypocrites that you are all acting like you care about idols mental health and how they feel
and can't even think if they would be comfortable or not with unknow people not calling them by the stage name they decided to use before debuting
And prefer to call them by their real name without even knowing if it doesn't make this idol awkward and uncomfortable
95% of the time the stage name is chosen by the company, mostly for 3 reasons:
1. to be easier to remember
2. to avoid confusion in case there's another celebrity with a similar name.
3. to fit in with the group's image
Their real name is made public, unless an idol states they don't want to be called by their real name then I don't see any reason why you should make a fuss about it. Most idols nowadays use their names anyway...
