Let's look at "tools" from a different angle.
Regardless of whether it's a Ouija Board, a Scrying Mirror, or something not even attached to spirit communication such as a gun or a knife. If placed into the hands of someone looking for fun and who has no knowledge of how to prepare themselves to use it, the tool can be a dangerous thing.
Obviously anything unused is "safe". However, it only takes one time to fire the bullet or carelessly call upon a spirit to consider it "used".
There are protocols to protect yourself and the doors you open. You can always close the door and purify the tools and area. There is no reason that these procedures can't be taught to people who want to use an Ouija board.
Obviously the 8 to 14 year old girl that a pink Ouija Board is aimed at in marketing strategies is not going to have the understanding to take these protocols. Actually, it really doesn't matter what the age is. There are people who think "Oh cool, let's do it", or they've seen it used in a movie or television show; thus they suddenly know how to properly use it.
I never said that there are people out there who don't take precautions. What I geared the article to be able are those who are enthusiasts; people looking for a thrill or a "wow" of an evening by disregarding the rules with tools or investigations to go looking for something.
And when you add in influence from television shows where people are off alone in a location to ghost hunt, and even use some of these tools (Ouija Boards, etc.) but show no protocols in preparing to use it .... the validity of what many of us do narrows considerably and the rise in entitling something as a fad or game can set in.
