Just found that on YouTube :

What do you think of that kind of "BJJ hater" guy ?
Not even a good troll job for YouTube.
The guy writes,"It demands to be very effective. * * * Brazilian jiu-jitsu doesn't have any punch striking."
He can't use idiomatically correct English. Why would you expect his criticism to be accurate . . . lol . . . rate the troll job about 0.5. Not even a full point.
