This is not an argument in good faith.
You can stand against racism without "howling at the moon", this is almost a dog whistle at this point for people saying that not standing for racism means being loud and brash, as if black people don't know any other way to stand tall. It's legitimately sad to see one of my own people use it.
You don't need to be chanting at a protest on the lawn of the White House to not "accept racism". It's a valid form of standing tall, but realistically, not everyone can, or is willing to do that.
But turning down opportunities with parties don't show any effort at all at diversity (or even worse, show racial bias), being willing to put people on the spot for their actions even if it comes at personal risk or embarrassment, being willing to actively advocate for diversity in cases where you have power to do so.
There are so many ways at a personal level to not just accept the state of things that are not "all consuming", to act otherwise means you're not even interested in having a genuine conversation on the matter, and just comes as an attempt at post-hoc rationalization of giving up.
