NO animal attacks purely on instinct, not even sharks. It's how they track prey. Finding Nemo wasn't a documentary XD
You know what? Sometimes you can't even avoid wolves. Sometimes they just attack. They're not all rabid and it's not all the human's fault. WOLVES HAVE KILLED PEOPLE TOO.
And you know what? Some people DO freak out for the mere fact that it's a spider. I freak out when I see house centipedes, and I kill them, but I am trying to find ways to get over that. I've yet to hear someone tell me about their deathly fear of wolves, but when's the last time you heard someone talk about arachnophobia? Spiders are NOT based on instinct. They may not be as complex as wolves, but they DO feel the basic emotions, such as fear and the will to live. Do you honestly think a spider, which, by the way, is TINY compared to a human being, would feel the need to run up and bite it? That would pretty much lead to the death of the spider-- you'd kill it if it bit you, wouldn't you? Hence, evolution wouldn't do that to a spider. That would honestly make no sense at all. You would die because of your instincts and not pass your genes on.
Wolves are not 'evil' just because of the fairytales, stop using that as an excuse. You know there are fairytales where the wolf is the good guy? *legasp* They're also metaphors, not 'stay away from the big evil wolfie or he will eet chu!' Funny how no one mentions that bears are used just as often, if not more, as villains in fables.
When most people see a wolf: Omg so pretty! So graceful! So majestic! It is a wild animal and I respect that, but it is still beautiful and I love it!
When most people see a spider: OMGOMGOMGKILLITKILLIT!
Honestly, which would YOU be more afraid of, a fluffy dog that resembles Rover, or a somewhat hairy, eight-legged and eight-eyed insect?
It disgusts me that some people think that 'lesser' animals, like spiders, are hardwired or instinct and just randomly attack humans ALL TEH TIEM. How can you say that spiders are not misunderstood? This sickens me.
EDIT: No one has died from spider venom in the last 100 years, and there are two deaths a year due to allergic reactions.
