The ones in real peril are the ones who do their homework, get the proper kit, learn the proper incantations, and don't just borrow the glass out of the bathroom to use on a sketched-out ouija board because they think they know what they're doing.
I believe in demons but the idea these books encourage children to participate in spiritual darkness is beyond ludicrous.
Shakespeare's Macbeth and The Craft have got far more dangerous incantations in them than anything you'll find in Harry Potter. So has Sabrina the Teenage Witch!
Wingardium leviosa isn't even pig Latin never mind proper Latin, and wouldn't work even if you did have The Gift.Locomotor coffee only works when my wife's in the kitchen (and I translate the incantation into English). I tried shouting Avada Kedavra at a very timid gerbil once and it didn't even fart.
WARNING: You can get complacent. For example, Izzy Wizzy Let's Get Busy is, was used on a children's programme in the UK, without the programme makers realising that it is in fact an incantation of truly apocalyptic evil. The mute yellow puppet Sooty to whom it was attributed, was actually a demon from the broom cupboard on the 17th layer of Hell, who was merely disguised as a hand puppet in order to manipulate Matthew Corbett (who I suspect was actually an ipsissimus with a glamour). That information really could save your soul.
Heh heh..

So are you a muggle or a squib?
