I think people underestimate the difference between being scared of something and an actual phobia. I have friends who are scared of spiders but my wife is actually suffers from arachnophobia. There is a huge difference and arachnophobia is very common and has millions of sufferers. Even seeing a picture of a spider in a magazine is extremely distressing for my wife and results in the magazine flying across the room and her physically shaking and sometimes crying. Many people who suffer from it even find it hard to talk about or write about.
Now my wife won't actually want to play the game (she thankfully tolerates my obsession!) but if she did the inclusion of spiders would make that literally impossible. So I can see why some people would like it removed, and I wouldn't have a problem if there was an option that just swapped them for a different skin (that wasn't spider like) that could be toggled on or off.
There is also such a thing as the way the brain works.
If you are constantly reinforcing your fear by even crying at a picture, you are purposly training yourself to have a violent negative reaction to spiders.
I have a fear of spiders myself, but I am quite aware that a picture in a magazine or on television cannot hurt me.
I in fact make a point as to not give in to the irrational avoidance urge.
There is no point whatsoever in training yourself to be deathly afraid.
And it is beyond ridiculous to petition to remove a cartoon image of a spider from a game because people lack the willpower to actually force themselves to deal.
Its a rich peoples disease. Dont you have anything better to worry about in your life?
