"Mina's one friend, lofty rhino, who insulted me."
I insulted you because you were, and btw, still are, acting like a pretentious jerk.
"I made the inference based on the thing your friend said. Like, material things. There was a reason for me to know he's a dumbass, because he made two dumb posts."
Not only that, but it seems that you're actually
quite delusional. If you really go to Princeton, the institution should be ashamed of that lofty-ass title you are toting.
Seriously, fucking educate yourself:

RIGHT HERE IN FUCKING BLACK IN WHITE IS THE EXAMPLE WHICH WAS SHOWN BY MINA'S POST:
The em dash in place of a colon
The em dash can be used in place of a colon when you want to emphasize the conclusion of your sentence. The dash is less formal than the colon.
After months of deliberation, the jurors reached a unanimous verdict—guilty.
The white sand, the warm water, the sparkling sun—this is what brought them to Hawaii
All Mina did was wrongfully place one hyphen instead of two which is commonly used to represent the em dash in type.
If you don't want to take two degrees in the field, and published material as proof enough, at least read some fucking blurbs.
Jesus Christ.
