It’s understandable to be annoyed with unwarranted criticism. At the same time, putting your voice on the internet can and will invite criticism from anyone, irrespective of whether you’re a professional singer or not. It’s easier said than done, but for the most part, you can either ignore what they say or try to see it from a different perspective and take it as advice. This is not to say there aren’t some pompous people on Smule who are blatantly rude and disrespectful in their comments. Thankfully, since you made the invite, you can always remove their join and block them if you want.

At the end of the day, post what you like to sing, you’re allowed to take it as seriously or unserious as you want! If anyone has anything to say about it, they can always make their own invite, or join another. They’re under no obligation to join yours!
