Can opinions be wrong?

Opinions are opinions.

Flat Earth is an opinion, and gravity is a theory. The difference is one is right and the other is wrong.
That's just an easy example of a technicality, but other opinions can be wrong too.

If someone were to say "Sonic the Hedgehog is better than Super Mario World", they would be wrong because Mario has better power ups and more levels which are better designed. Luigi's gameplay is also much deeper than Tails' abilities.

If it's based on incorrect facts, then yeah. Like if I said Trump is an awful senator.

No, if it's wrong it's not an opinion.

Like if I say Super Mario World has only 7 levels, that's not an opinion. That's just me being wrong.
