Um, no.
I can quote who I want. This is a forum. If you don't want to discuss with people, you can ignore my quotes or not comment. Like I said, I never said Ariana is better than Taeyeon, but listening to them both sing you can tell they both have good singing technique. But saying that Taeyeon trumps Ariana from an obvious Taeyeon fan who does not seem to know a lot about vocal technique themselves comes off as biased.
Tbh, the only one sounding biased right now is you, especially if you start using unnecessary ad hominems.
Both Ariana and Taeyeon can be good singers, and still one having better technique than the other. That doesn't make one singer any less of a good singer, simply that the other is technically better.
Taeyeon is a better skilled singer than Ariana. That doesn't make Ariana any less of a nice singer to listen to, just like Hyolyn being a better skilled singer than Katy Perry or Ariana wouldn't make them any less singers to enjoy. For the rest, believe whatever you want to believe.
