I'm sorry the concept of a rhetorical question throws you for such a loop. I tend to speak to adults as if they are adults, and forget that some just haven't reached that level yet.
Here's an explanation for you to refer to, in case I forget and do it again down the road:
rhetorical question: a question asked in order to create a dramatic effect or to make a point rather than to get an answer
Once again, I said "Interesting perspective", which tells the reader that i already know the answer to the question. It's kind of like saying to your drunk cousin "How'd you like me to kick your ***?" Followed by "I didn't think so" when they STFU.
The question isn't really looking for an answer. It's rhetorical. The "I didn't think so" reinforces that the question was rhetorical and not looking for an answer.
Got it?
