Throwing a tantrum as soon as you don't have anything left to say...

If I had left it at "lol no" (it was a funny point just looking at the country you're talking about...) at least I could see why you're upset.

But instead I still proceeded to break down why you're wrong in quite a detailed manner and school you a bit on the topic so you can go forward with a better informed view of the country.

The customary reply there isn't a tantrum, it's a "thank you" or a "that's interesting for me to learn". Some people really do forget how to behave the moment another person doesn't agree with them.

You're really full of yourself, aren't you?

But fine, thank you for schooling me in arrogance.
