You're comparing two things that are actually quite different. In your example, the other person thinks that you are being honest, and is mistakenly trying to help you overcome your unlikely sequence of obstacles. In the example you're comparing it to, they are trying to confuse you out of your principles by showing off their verbal skills. Here is an example that I think gets at what you're going for:

"Quit making fun of me for my big nose."

"Hey, that's a legitimate form of humor dating back to the third century BC, when Prodigious wrote..."

"That doesn't have anything to do with my feelings, could you just stop?"

"Facts don't care about your feelings."

And so on...
