@Shadow: -...So dogs were so annoying to you, their annoyance induced hate and fear towards them in you?

-Dude, this doesn't even needs citation. It's a proven fact. If you want me to explain it.....things that cause fear to us, are, like almost everything about us, genetic. It's information that can and will be passed to the next generation that heredates the trait.

Snakes, spiders and rats have, since ancient times, been considered harmful, dangerous creatures to humans. Danger causes fear. Fear is information. Information is divided among the genetic traits. Result: Humanity for the most part fears those things on instinct, even if they have never even seen one.

However, like everything, genetic traits are only a base, an X in the equation. While one can, say, be afraid of clowns because they got that trait from their dad, it doesn't mean it shall stay. Experiences can easily change our traits. Genetics only decide what are those traits to begin with.

So basically, most of us fear snakes, spiders and rats on instinct because everyone since our great great great ancestors feared them and the fear has been passed among the genes for generations.

However, it also applies the other way. Dogs have been an important ally of humanity. They can be smart, capable fighters, and effectively do a specific task if trained and sometimes even if not. It's been like that since ancient times, and as such humans consider them friends, allies. And just like fear, that is passed on our genes.

This means that most people either don't think anything of dogs, or see them in a positive light. But just like with the other traits, experience affects this. A terrible experience with a dog can easily change one's instinctive friendliness towards them right into fear and dislike.

In other words, love of dogs, and hate of snakes/spiders/rats, is all genetic, and like all genetic stuff, it's passed and been passed since ancient times to each following generation, so we all instinctively begin loving dogs and hating those 3. But, experiences can easily change that, because genes are only a base, and experiences mold it.

As such, yes, it's not normal to hate dogs or love those 3 without a reason. If there's a reason, it's normal, but if there is none, it isn't. Got it memorized? Ask any expert or non-expert on genetics, they can easily tell you the same thing.
