Just a reminder: the “would a reasonable person question their impartiality” test is not an actual normal reasonable person test, to the extent there is such a thing. It is a stylized, history-encrusted, precedent-confined test based on what octogenarian white judges thought was reasonable.

/2 Put another way the “reasonable person” in the test is a “reasonable career lawyer who is firmly ensconced in judicial culture and shares a common set of assumptions and beliefs with the judiciary.” What’s reasonable to you may vary.
You may not like it but that’s the law.
I think it’s reasonable to assume that if a person says, "I won't control an insurrectionist in my house." It can be surmised that"I’m not going to bother to control an insurrectionist in this society that I am ostensibly in charge of." Is also true.
