I’m half Chinese. My wife is Chinese. No Chinese or Asian that I know are offended. In fact, it looks great.
Kids love it because it’s colorful and cool. Also, it’s in line with the ninjago series, so why is this different?
Western people need to stop being offended on behalf of other cultures. You being offended on our behalf is true racism...racism of low expectations.
I often feel complimented when other cultures try out our cultural foods, clothing, and other festivities.
If you don’t like it, then that’s your choice. But don’t dislike it on behalf of other people.
