Mine don't scare me, but I also don't handle certain species because they are aggressive/more venomous. I say handle smart not fearless lol. They give you pretty decent warning signs, as long as you pay attention and show them respect there shouldn't be anything to be afraid of.
I don't have a tarantula as my wimpy husband will not allow one in the house. I have never been afraid of spiders and actually wanted to be an entomologist, love me some buggies!
