Well I get what he meant. Sometimes ppl put no effort in to trying and you can see the playful sometimes insulting ignorant attempt.
However, there is an excuse. Being raised in Asia and being raised in the Americas cause you to develop different parts of your mouth/voice which makes it harder for you to speak in certain languages especially the more difficult ones like Mandarin. I forgot which language it was that makes it easier for you to learn Russian and Mandarin. English born speakers will have a harder time though. It's why things like accents exist and we can tell where a person is from when they speak English sometimes.
I try to make an effort with the names though given I've across similar with my own name.
