Not really. Yes, she has said she supports BLM, but she also still stands for the national anthem, has said multiple times that it is an honor to rep the US in the olympics, and overall seems like a good person that just has a stance you disagree with. As I said above, you have no clue what it takes to be a gymnast. Most of the apparatus requires you to solely use your inner ear for spatial awareness. That is why it takes many, many years of practice to do those skills. If, for some reason, your mind starts confusing those signals then you are SOL. If you think a person can spot the ground in time while doing a double back flip with three full twists you're delusional. And trying to throw a skill like that without that spatial awareness would be akin to playing russian roulette. Beam is different in that its uses less spatial awareness as you have a at least one hand or foot on the beam with the exception of a few skills. If she does compete, she will probably remove a few of the more demanding skills and focus more on execution.
Some people will always be insanely jealous of other's accomplishments and thus need to comment incessantly.
