I honestly have no idea how to respond to you.
Where did I say anything about homophobia?
I have already made the point about internet safety, if you read the thread (or even, you know, just the posts of mine you're responding to). I've already made the point that the worry here is a child innocently clicking on something nasty. Other people have said this too.
But, children searching for things about 'boys' or 'girls' is not the same think as searching for porn. It is really disturbing you think it is. It may not even really have anything to do with sexuality or interest in sexuality.
When my daughter was four and went into reception, some of the little children at school asked the older children whether it was true you could have two mums. And the older children, all of ten or so, answered learnedly that it was. When she was five, she and her best friend sat in the back of my car and her best friend confided in her that she was going to marry a lady and have several dogs and no children.
Should I be terribly, terribly worried about these sorts of innocent questions, which are absolutely on that worrying trajectory that ends up with ten year olds googling shocking things like 'kissing'?
Of course not.
Children at this age are curious about the world, about each other, and about themselves. But they are pretty innocent. All they need protecting from is the horrible fact that, because we live in a world the world we live in, their innocent questions might bring back very disturbing results if they ask the internet. So the OP should do an internet safety talk, even though she says there are protections on her internet already.
But please can we not start writing fantasies about you being accused of homophobia, or about children seeking out porn? It's got nothing to do with that.
