Your post amounts to "I'm glad these idiots found a voice, now that they finally affect us all, we can do something about it". But your assumption that they affect us all equally is not supported by this story, otherwise all passengers on that plane would have been taken off and screened by police.

I think you fail to realize that these idiots affect mainly minorities, as that is how uneducated minds work: they can't see past their own identity (and by the power of numbers, most idiots are white). So what you're effectively saying is "I'm okay with idiots harrassing minorities".

(edit to add an unwarranted disclaimer: by "idiot", I'm not referring to the lady in the original story, but to the OP's description of the "tragically ignorant, in need of raising their bar")
