Okay well those of you who use Facebook (I don't but learned of this from another forum), there's a story doing the rounds that Asda (a UK store similar to Walmart) has produced a child's t-shirt with that very statement on it... "Boys Will Be Boys".
Someone on that forum relayed the Facebook story, saying that she agreed that it was a terrible thing, a disgustung thing for Asda to have done and said that anyone who wanted to complain should email Asda directly.
I just couldn't see any untoward intention and tbh what the fuss was all about, everyone else in the thread agreed with me too, that it was another PC Brigade thing but, some of the comments I read were unbelievable including this which was the worst:
"'Boys will be boys' is essentially normalising r.a.p.e culture at its most extreme extrapolation.
I'm left thinking at what point in a mind could it reach that interpretation? We have a 9yo and 7yo, would the world, if they wore this tee in the street consider them as potential rapists, now or later?
Pretty unbelievable isn't it but because there are some, in the minority yes, but there are some who see a sinister element, it does make for discussion.
The replies so far have shown the most common understanding which is that the expression means 'boys doing as boys do; climbing trees, being mischievous' - just that.
