Wha? All opinions, by their very nature, are subjective by definition. Are they not?
No. Opinions are neither objective nor subjective; however, an opinion can
only be
valid if it's about something subjective.
Example; whether or not something tastes nice or tastes gross is subjective, and as such believing that either is true would be someone's opinion. The sky is objectively blue, and as such holding an opinion that it is, in fact, not, would be invalid.
Many people attempt to avoid arguments by declaring that opinions are subjective, and implying that subjectivity, in that case, means that one's opinion is incapable of being wrong, which is definitely not the case. It's also important to note that the point of debate in the first place is an attempt at organizing subjective ideas into objective ones; the line between subjective and objective is not as distinct as people tend to assume, and the pervasive idea that 'quality', as an idea, is an incomprehensibly complicated notion that's essentially impossible to quantify to any degree is just flat out wrong.
Rather than trying to make your opinions unassailable, consider that the wise man knows that he knows nothing.
