I wouldn't want a person who could be aggressive to a vulnerable animal around my child, it's clear she has a nasty temper and was attacking the horse in front of young children.
It does not paint her character in a good light at all.
This. ^ What a vile, abusive, aggressive woman.
Gotta love the 'how does this affect her ability to teach children' brigade! 
No comments about the appalling behaviour towards this lovely horse.
Speaks volumes about those posters.
I hope the woman is sacked from her job. As you say, who wants their children being around a vile woman like that?
