Are people in this article really suggesting that the 100% emoji is racist? You can never get a perfect score or agree with anything again because a small number of people have used that number to mean something else and now somebody will interpret it as a hate crime.
At first they were arguing that somebody writing "shit" in an exaggerated way, and the occurrence of two other numbers and an elongated asterisk were Nazi symbols, and they could be, but the only evidence is that somebody said they thought it was too many coincidences. I don't know enough about the circumstances to say it is or isn't intended that way. Management apparently thinks it isn't. But saying multiple people reacting "100%" to a message they agree with means they're all using the number 100 as a sign of white supremacist solidarity is ridiculous. What else are they going to do? React with the "OK" hand? No, the ADL also decided that one is racist. React with thumbs up? No, younger people have decided that one is rude.
