I can understand not liking a child (When I say child I'm talking about 2-10) or a non-human animals. E.g "I don't like dogs."
I don't understand how someone can say that they hate dogs or a two year old child.
A dog and a 2 year old child are both "innocent", the lack the cognitive ability to know right from wrong.. So, I don't understand how you can hate a dog or a 2 year old if they bite you or ruin a television or because they are annoying you.
In addition to this hating all dogs because of the actions of one or a few dogs isn't right.
