There’s a big difference there. The eye gesture is making fun, purposefully and generally in a derogatory manner, to the anatomy of the East Asian populous. The tea gesture or awesome Russian dance are poking fun at a culture. It’s not a huge difference, but it’s one that matters. English people may be offended by the tea gesture, but we not attacked their humanity or anatomy. We have struck a cultural difference at best.
Honestly, it isn’t hard as an athlete to say that there are other ways to celebrate without mocking people. I can already think of a few for teams qualifying for Tokyo.
