So many flawed logic in here...
Fandom is not a matter of logic, it's a matter of opinion and a matter of personal likes/dislikes. You have your opinions about Socko's singing, and other people have their opinions. People have the right to have their own opinions about things. You need to stop telling people that they're wrong and that you're right, because there is NO one, single correct answer in this matter. What you're discussing is NOT something that is quantifiable. It's not objective, it's subjective. Just because people don't agree with your OPINION does not mean that they're thinking incorrectly. It just means that they disagree with you.
If you want to believe that the reason that Socko gets so many lines is because she's the best singer in BK, then ok. That's YOUR OPINION. Consequently, if others want to believe that the reason that Socko gets so many lines is because she's got a cute face, then that's THEIR OPINION. Both sides are entitled to it, and both sides need to respect the other. Failure to show that respect is what gets people reported to the Mods.
