It would be racist however, if you told that person, 'oh, no, you MUST be this person because all asians look the same' or make an insult based on the generalisation or ignorance of a race. That's basically what racism is, insulting someone purely because of their skin colour/race. So yeah, thumbs up for 'thapwnzor'! ^^
Have a nice day. :)
