can TKD be used to take on mutiple attackers?

I have seen demonstrations where 10 or more attack one person

No style is geared toward "taking on" multiple attackers. If there are several attackers intent on killing you,you are dead,I don't care what style you do. The best advice I can offer would be to stay on your feet and get away as soon as possible.

In my organization when you reach black belt you start two on one freestyle, when you get higher the amount of people goes up 3 on one and so on. I agree that if you have like 10 on one ya i would say my prayers and hope i dont die but two on one is managable.

NO

I think everyone would agree that 10 attackers is just movie stuff but I'm going to state it can't be done w/ any regularity against even 2 people.

2-on-1 / 3-on-1 freestyle is a good exercize but not as realistic as your instructors would have you believe.

I'm not even saying the attackers are intent on killing you, just controlling you (as in an arrest).

TKD is as effective as any striking art against multiple attackers, and far better than grappling styles.

Sorry, I think it's a fair point. If your grappling style doesn't equip you for such things (in other words, if you are stupid enough to go to ground in a multiple attacker situation) then you'd be better on your feet and not getting close to one person when it is a liability and likely to get you a riverdance rehearsal on your head.

With striking arts the emphasis is on moving and avoiding and counter striking. While not fool-proof it is probably a better option.

Personally I think the Carl Lewis approach is the better option against multiple attackers.

use a gun
when you become more advanced in TKD like red or BB the start teaching you on weapons...in my opinion the best weapon for more than 3 attackers is nunchakus...
