I've said it before and I'll say it again, anybody who calls any firearm a "toy" (even in jest) probably shouldn't own one of have any children because they fail to understand the inherently deadly nature of firearms and therefore are a danger to both themselves and others.
I don't care if they are just making exaggerated comments about the build quality of a particular firearm either, it's just a remarkably stupid thing to say about something as harmful/potentially deadly as a firearm, and I personally feel that those who make such statements are too lacking in due respect towards the inherent danger firearms possess, ergo they shouldn't be trusted to safely handle them.
