Maybe there would have been a better way to handle this, but I can't believe for a moment that it is worth even raising a fuss over. The teacher was obviously thinking about ways to punish that wouldn't be abusive or scarring.
While I agree that teachers need to be watched in order to protect our kids from potential bad ones, I also think we need to stop micromanaging every little thing they do or say. They're people too, and since in America most of them are left with the job of raising somebody elses kids, they certainly deserve a break more often than they get, and shouldn't be suspended over every single little thing they do or say when it really never hurt anybody.
Once upon a time (or so I'm told and have read), parents supported teachers and worked together to make sure their children were respectful both in and out of the home.
Now there's this whole "my kid is special and HOW DARE YOU touch/speak to/look at my child that way?" attitude, and it's really just a bunch of egocentric bull**** that most often comes from parents who can't even deal with their own lives, much less their kids.
I do realize that this isn't always the case, but it sure seems like it a lot of the time when I read news articles like this.
