It's called a hypothetical. It's a logic exercise. From certain people all you get are idiotic responses and I generally know which ones.
>>It’s called a hypothetical.<<
What you posed was NOT a hypothetical. It was a nonsense scenario geared to try to make a point by rigging the question (this is called “begging the question”).
What if every single kid came back to class with the measles? What it we packed them off to the moon? Same probability. And despite that I gave you a proper answer — you just didn’t like the facts being used since they do not conform to your not so hidden agenda.
I don’t have time to teach you forensic theory. Suffice it to say your point was as lost to you as your weak and pathetic attempt at argumentation. I suggest you stop while you are not too far behind.
