i don't know how many times i have to keep saying this - racial oppression develops culturally, meaning there could be no logic to it but it becomes racist anyway due to the usage by racists for that purpose. for example, a lot of slurs have literally no etymological meaning, such as the "G" word used against Asians. you are trying to make racism seem logical, when it isn't and never has been.
no, but being black could be described as a "din" interestingly enough, which Islam describes itself as, as the English word "religion" and its connotations did not exist in classical Arabic. Would you like to learn things from an Islamic perspective, considering you "have never knowingly interacted with a muslim"?
No one asks that you follow ramadan don't work on fridays or quit eating pork. You can even draw mohammed in your own home. But drawing muhammad in our society with it's context has been made into a racist attack on Muslims. I don't know if dogwhistle is the right term, but it is similar, i think.
