Absolute bullshit. I've seen Natives get hit in the face with a baseball bat, smile as their teeth fall out, and fuck up a bar full of loggers. I was scared for my life. You have no chance of knocking out these beasts, especially if they have fetal alcohol syndrome.
I live on the West coast of Canada and we have no shortage of Natives. They're like what Mexicans are to people in the United States. They're a mess, but my Lord are they ever tough. My two friends are German and Native and they used to roll around on the ground throwing fists directly to each others' faces for a good 10 minutes non-stop. If this race could clean themselves up, I don't see why they wouldn't fair well in combative sports like MMA.
Avesher, you should know better than to bullshit about something as blatantly obvious as this. There may not be many Natives out East but there are plenty here. These dudes are indestructible, especially if they have fetal alcohol syndrome or if they've just got alcohol in their system. I've seen the sloppiest Natives beat the ever living fuck out of a group of TOUGH people at parties and whatnot.
