Ha! Don't be pained too much. I had to go back a look through my last posts to know what you were talking about! I had no idea who you were and don't carry grudges.
But anyway..
These people say the most incredibly stupid things. Actually even on this forum is some of the other thread about the shooting people are saying the same thing.
No good guys with a gun could have made a difference. The best thing to do even if you were armed is cower in a corner or run. It is sad.
I understand that the terrorist had some body armor on, I don't know exactly what, yet.
However, keep in mind, that:
1. I am sure his weapons were not armored, 9mm handgun slugs and up, would definitely damage the trigger group, and magazine throat and magazine of an AR-15, or a shotgun. A 100 round drum magazine is a large target, and somewhat fragile. Denting the receiver will also take the weapon out.
2. Whatever is used for a faceplate or a screen, even on a bomb squad helmet, will quickly lose visibility after receiving bullet strikes.
3. Gloves or mitts on the hands, that have enough dexterity to fire and reload a weapon or shoot a handgun, will not provide much protection to the hands. Bones in the fingers and wrists will be broken and blood will be lost, and unless the shooter was shotup with speed or painkillers, the pain will quickly be disabling. Basically you just need to cripple 1 hand to end it: when the terrorist can only shoot 1 handgun at a time, it will be over soon.
4. Shots at the lower legs and feet, especially when moving, will throw the shooter off balance and down on the ground. It is not easy to get upright and reoriented while wearing all this gear, especially while taking hits.
None of the above shots would be easy, or safe. But,
they could have made a difference. Multiple defenders would make a BIG difference, so the terrorist could not concentrate his fire, for long.

I watched the Dark Knight Rises, tonight at an unposted movie theater. It was well attended. I sat a few seats in from the aisle, with the only front exit in a close field of fire. 3 times an usher checked the front exit during the movie. I checked it before I sat down.
I checked the front exit visually a lot more often than that. My XDM had the long magazine in it, and a spare in the jacket pocket.
One thing the Israelis are right about: you cannot let terrorists stop your activities, chase you up a tree, or down a hole.
