When you have an answer to a question but the person you are asking is not allowed to answer your question but the question makes the reader/person being asked the question think like a normal rhetorical question
"Don't I look adorable? " the answer is yes but the person being asked the question is not allowed to answer because that is the rules of an unrhetorical question.
A sarcatorical question is a question asked sarcastically with no desire for a legitimate answer. Often used to allusively insult a debate opponents argument, or to state a bigoted opinion in a nefarious attempt to seem genuine with the option to feign ignorance if criticised for it (see: sealioning)
Example of a Sarcatorical Question : "If slavery was so bad, why didn't black people run away?"
