Once again, we don't know the teacher did any such thing. We have a girl's Nosebook post, and that's all we have. Are you in the habit of hearing one side of a story and then deciding, "guilty, off with their heads"? I'm not.
Already on Snopes
I read rather a lot. So yes, I"m an 'off with their head' hangin' judge type. Be nice if I could count on living for centuries, but as it is, with my reading list, I don't have time to read every little thing. The particular article isn't the important part. Could eliminate it altogether and still have pleanty of incidents to cite.
That's my previous point -- how many of those "previous incidents" are similarly Snopesable bullshittery? Do they in fact even exist? Already I've got several "disagrees" in the thread and not a single "agree" even though everything I pointed out was dead accurate (not that that matters, truth will out no matter what) and already several posts, including from you, completely ignored that reality and went on with the bullshit OP as if it were a real story. And you can bet there will be more to come. The Big Lie syndrome.
Bottom line seems to be that people want to believe what they want to believe and facts aren't going to sway them. Bottom line, there are those among us right now who believe the OP to be factual for no other reason that a message board OP pretended it is. And that kind of gullibility, that kind of blind acceptance of a perception floated out for propaganda purposes, is more than a bit scary. Propaganda sells better than fact. That's the whole reason this crap ended up on TV stations and websites in the first place.
