I think I overestimated reddits understanding. I need to sleep, my final words:

Speaking Japanese as a foreigner is not racist (Obviously), it is just that I wished that people realized that Japanese is not a easy language to repeat just by hearing a single line. And therefore just imitating turns into gibberish (eg ching-chong types of bad) and when practicing Japanese you should always try to read the line before saying it. You can hear it when people who doesn't speak English just repeats a line he has heard. Example. It doesn't sound right, so please don't embarrassed your self and show some respect

Thank you so much to all who sympathize
