They are simply pointing out that "racist" and "bigoted" are just as ambiguous in the exact same way as the "evil", "harmful", "good", "negligent", "bad", "unethical" etc he mentions for the other licenses.

"bigot noun a person who is obstinately or unreasonably attached to a belief, opinion, or faction, especially one who is prejudiced against or antagonistic towards a person or people on the basis of their membership of a particular group."

If being a bigot is good/bad/evil/harmful/unethical or not depends entirely on who is calling you one, and what you or society thinks of them. If you think that just because someone is a MAGA/Nazi/Tesla owner that they are bad, congratulations, you are a bigot.
