This is insulting and just a shame...... Don't wear a belt unless you feel you can back it up.... And more importantly out of respect for the martial art that you're practicing and representing, don't disrespect the traditions and those who have come before you.
I travel to Europe quite a bit, I may need to find this "red belt" and ragdoll him.... I'll do it on video too, and I'll make like my buddy Ruben Alvarez and tear this guy up for being a fake.
