It's about a combination of stealth and the sensor/avionics package -- the ability to detect and identify SAM radar systems and launchers, and chart a path which minimizes likelihood of detection, aided by the aircraft's low radar signature, while enabling strike operations to take place. If you're arguing that the F-35 is not invisible, then you're attacking a strawman.

The F-117 was central to SEAD operations during Desert Storm, and the F-35 is regarded as the most credible SEAD platform in the USAF inventory today.
