I tend to avoid these discussions - but so far it hasn't got TOO heated!
I'm with the camp that says it's just a word, and the issue of child abuse has been sensationalised.
By that I am IN NO WAY implying that it is not a serious offence and should be punished appropriately.
However, by far the majority of child abuse (both sexual and physical) takes place within the family. Sad but true. If you believed the press, you would think that there were paedophiles on every corner.
I think it is important to teach children not simply about stranger danger but also about "appropriate behaviour" (in the gentlest of ways), ie NOT to be persuaded to do anything that feels uncomfortable or wrong, or to "keep something secret". However, by over-emphasising the stranger danger aspect, we are running the risk of teaching our children not to trust ANY adults, whereas the majority of people out there are decent human beings!
I believe we have become overly paranoid - largely due to the sensationalist press - and that THAT is what is posing the greatest risk to our children - reducing their freedom to roam, to discover the world for themselves.... to have fun and LEARN!
Anyway, I think I have gone a wee bit off the subject, so I'll stop there!
