Eh, there's quite a few misconceptions about tarantulas. Like when people (even the one that are supposed to 'educated') advise other people they're not venomous at all or have had their 'venom glands' removed. It's about as true as the 'fact' that all parrots can and WILL talk. Because, all birds talk, right?
Joking of course.
I've handled some over the years based on the situation, but I've never had them just to 'hold' them or 'freak people out'. They're mostly like fish tanks for me: I guess is a good description. Besides, some species I've had, you would seriously regret it if you tried to hold it most likely. There's a balance between experience and just plain stupid, IMHO. That balance is different for everyone though.
