I have a hard time believing that. Lots of parents are afraid of dogs, but that doesn't give their children the visceral irrational revulsion towards dogs that arachnophobes have towards spiders. I've never heard of someone who can't even look at pictures of dogs or birds or bears, whilst it's very common for images of spiders to make people very uncomfortable.
As far as I can tell, not being afraid of them has to be learned. I cannot find a source, but I recall reading that even people who keep spiders as pets, still have a raised heartrate when holding them.
