wow it is important to say something and then instantly block the person, very mature and not 5th grade at all.
On a general note - there is a thing that's called "satire" and another is "humor". Trust me you won't last if you take everything seriously and close to heart, it will give up (not a threat btw, like you did, just medical statistics).
Civil discussions about not understanding something are ok, we're different after all, and may not understand each other in the end anyway. But don't cross the line.
