The stupidity is that if you made a Venn diagram of Boba drinkers and people prejudiced against East Asians, there probably isn't much crossover. It's like making an antisemitism ad saying, "You love matzah ball soup, so say something to the people hating Jews."
FTFY. No one saying its a good ad, just not racist.
Essentially, different cultures are good as you enjoy some aspects of their culture. Therefore stop people from hating on other cultures.
