I don't believe it was ever sold as equal in capability to F-16 in the air superiority role.
You can believe that if you wish, but you are quite wrong.
You're disregarding on-the-record, sourced quotes that say that not only is the F-35 equal to the F-16, it's dominant over every threat and competitor out there.
Do you think that your determination to ignore all evidence that contradicts your opinions is the reason for the negative attitudes about which you constantly complain?
