From Aikiweb.com:
“What is this fear that by doing an art like Aikido we can be beaten by someone doing mixed martial arts? Is this a worry that you live with on a daily basis? There’ll you’ll be at the grocery store when, suddenly, you are accosted by the local gang of MMA practitioners… Really, I can’t honestly say that I know even one person who was ever in a fight with another martial artist on the street.”
