Ah I understand.
Your position is that F-35 dominating other fighters in Red Flag isn't really indicative of anything since they weren't actually shooting live missiles. They can't figure out who can actually see their opponents first, get into a position for a lock, evade, etc. nah these exercises they run every year produce no meaningful information to evaluate how well different aircraft perform against each other in air combat. Complete boondoggle. We'll take that further and say by extension the F-22 doesn't make a good interceptor, since there is absolutely no combat evidence that it is the dominant air superiority fighter they claim it is, we don't believe in useful data from simulated combat.
Therefore Westwall's claim that the F-35 won't make a good interceptor stands, regardless of dominance in these silly Red Flag exercises.
You can't make up comedy gold like this.
